Yes. "small". ;)

I agree that the flat layout can be hard to navigate. While we are not
at a scale that needs something like sparse-checkout, but this wide root
directory cannot be reduced by cone-mode patterns. This is meaningful
only for niche cases like "I only care about Documentation/" or someone
testing sparse-checkout performance on a copy of this repo. It's something
that I do think worth mentioning whenever such a large refactor will be
undertaken.

There are two really big disruptions that this will introduce. I bring
them up only so that we can discuss them and make sure we handle the
communication to the community and appropriately time the merge of this
series:

1. It will conflict with most patch series in flight. How can we
   communicate which topics will be caught up in the rename before it
   merges, which will be modified at merge time by Junio, and which
   will need to be sent anew on top of this rename?

2. It will conflict with forks that have long-lived history that is
   merged with or replayed on the core project. The examples I know
   well are github/git, git-for-windows/git, and microsoft/git as
   discussed in [1].

   Something that I think would help for these cases is for the rename
   to be done as a solo topic merged into 'master' on top of a major
   release, such as immediately after v2.54.0 (or similar). This would
   allow a merge or rebase from the previous checkpoint to update to
   the rename without any other upstream edits causing further conflicts.

   Fork maintainers could then decide if they want to update their forks
   onto the rename early in the release cycle or as part of the next
   release cycle. My preference would be to update as part of the current
   release cycle so any changes during the release cycle automatically
   incorporate the change similar to working with the core project. (I
   am not a maintainer of any of these, so it's not actually my decision.)

Finally, I looked at what's left after your renames and I see that the
root directory has these categories of files remaining at root:

* Dotfiles that must be at root.
* Documentation that must be at root (README, code of conduct, etc.)
* Root build logic.
* .c and .sh files for root-level commands (git, git-*, scalar, etc.)

Of these, I'd be interested to see if there was value in moving this
final category of file into another directory, say 'cmd', 'commands',
or similar. It's the only remaining knob that I think is technically
possible to further trim this list of files.

Did you consider moving these files, too?

_If_ we were considering moving these files, then I'd rather make
one big rename change instead of repeating this exercise multiple
times.
