I think it's relevant in this case if I point out what the gitconfig and
gitattributes files contain on macOS. The gitconfig file sets up the
default credential helper, and the gitattributes file sets up default
diff helpers for Objective C and Swift.

To my knowledge, I believe what other distributors (including Homebrew)
do is they provide the system configuration file with default options if
one is missing, allowing the user to retain or delete these options as
the administrator sees fit. Apple may or may not want to do that, but I
believe that's probably the way that we'll choose to support.

While distributors will of course customize Git in whatever way seems
most appropriate, I think it's better if those customizations are
editable by the user, since that makes it easier to write per-user
configuration files that are consistent across platforms. For a tool
like Git, that can be quite helpful.
