My two cents:

1. I think he is overly obsessed with renaming. He seems concerned that
somebody will show up, make a big renaming patch, and then break your
system. Guess what? They can also show up, make a big code change patch,
and then break your system. In either case you have to review the
changes before accepting them, and it is up to the version control
system to show you the changes in a way you can understand.

2. I see the same old "git developers decided renaming wasn't
important" argument. I think this is bogus. I think renaming _is_
important, but I actually prefer git's approach of deducing renames,
because it reflects a fundamental property of git: we track states, not
changes, and git doesn't care how you arrive at each state. So I am free
to use a combination of git commands, editors, patch application tools,
or anything else to get my tree to the right place.

3. He doesn't like that git doesn't track _directory_ renames. This is
not a fundamental problem with git's approach (which could deduce
directory renames after the fact), but rather comes from the fact that
directory renames are controversial. That is, even if you know (through
deduction or because an explicit rename was recorded) that "subdir1"
moved to "subdir2", that doesn't necessarily mean that new files added
into "subdir1" should make that move, as well.
