Thanks for the perspective on this. The --filter-blobs[=<size>] should
be less likely to collide with an alternative definition of "partial".

While we are thinking in this space, what if we had a "partial-clone"
builtin? It could be a light wrapper around "git clone" where

  git partial-clone [--limit=<size>] [options] <url> [<dir>]

would do the same thing as

  git clone --filter=blob:[none|limit=<size>] [options] <url> [<dir>]

Just spit-balling here.

In the meantime, I'll work to adjust my patches to only be the
documentation of the --filter option.

Thanks,
