I would actually be in favor of merging this before v2.22.0. It's not like this is a feature we need to perfect, we just integrate upstream changes.

Similarly, I think it would not hurt to merge this before v2.22.0.
Granted, it does not fix a regression, but it's not like it will introduce a regression, either.

Not sure whether we want to fast-track this into v2.22.0. There is a risk.
But then, the longer we ship with `--filter=sparse:path` *enabled*, the more we invite users to actually try and use it.

As agreed previously, I'd be in favor of keeping this out of v2.22.0.

I actually do not see any benefit of this documentation change cooking. The most likely people to "cook" this is new contributors, and they will not see anything that is in `next` in my experience.
But it does not *need* to be in v2.22.0, either.

This is not a new regression, so by your standard it should not get into v2.22.0 this late in the game (and I agree with this standard, as there is a risk of regressions here).

I do dream of the day when we can just get rid of the entire non-smart HTTP stuff.
And I do dream of the day when we can switch `git daemon` to serve via smart HTTP, i.e. run `http-backend` internally. And then we could get rid of the git:// protocol, too.
But I digress.
If anyone wants to have my opinion on whether to merge this before v2.22.0: I don't think so, it is not critical enough, in my mind.

This is an older regression, so it should probably be kept in `next` for now.

Same here, this is a super old regression, and it will not hurt to cook it a bit longer.

Quite honestly, I don't care about `request-pull`, for what I know, this is shipped in Git for the exclusive use of the Linux kernel project, which is a bit funny.
In any case: very old bug, so its best home is `next` for now.

I guess it would not hurt anybody (and get a bit more exposure) if it was merged before v2.22.0, but it does not fix a problem introduced in this cycle, so...

I am of two minds here: as far as I can tell, this fixes a regression that has been introduced in 548719fbdc4c (clone: partial clone, 2017-12-08), so it is super old.
On the other hand, the partial clone is a young feature and *just* picking up steam, so I'd wish we could have this patch in an official version rather earlier than later.
But I can live with it living in `next` for now.

Absolutely, there is no need to force this into v2.22.0.
Having said that, I already integrated this into Git fo Windows v2.22.0-rc2... So I guess users on Windows will tell us if that broke anything ;-)

As with all things partial clone, I am of my usual two minds: I consider it an experimental feature, still, so I'd love to move faster on it than on other features. On the other hand, every such change risks introducing regressions late in the game.

With userdiffs, I am pretty convinced that the only way we can cook them really effectively is in official versions. I don't think that I know of any Octave user who builds Git themselves (and yes, I know a couple of Octave users, came even close to work with the group who started it in Madison WI).
So I'd be fine with this still making it into v2.22.0.

While not an old regression, it was not introduced in *this* cycle. So I'm fine with keeping it out of v2.22.0.

Makes sense, too. That's an old regression if I'm not mistaken.

Are we really sure that this is a good option name? With that description, I would have expected `--recurse-submodules=follow-tips` or some such.
In other words, I would have been in favor of keeping this in `pu` for a little while longer. But it's already in `next`...

As with the `GIT_DEBUGGER` topic, I am not so sure that it makes sense to cook in `next`, as it will hardly get any exposure, if any at all.

I am in favor of cooking this a bit more, too.
Hopefully it is useful for you to hear my thoughts on those branches? If not, please let me know, I do not want to impose my opinion on you.
