That makes sense. I'll reword this bit.

I'll try to clarify this, but I think we really should have some bit there about historical tools. Realistically no new git tools produce these, so the user needs to be made aware of what the trade-off of turning these on is.

The reality of that is that these objects are exceedingly rare, and mostly found in various old repositories. Something like that need to be mentioned so the user can weigh the trade-off of turning this on.
