Indeed. "always root:root" looks too restricted and generic issue
for me. I've already written an initial patch adding GNU-tar-like
options:

https://github.com/git/git/compare/master...mpsuzuki:pullreq-20171227-a

but it seems that more works (e.g. feature testing script)
are needed to propose something to git maintainers.

Also I've written a trivial patch for this, and just filed it
to bugzilla.

https://bugs.freedesktop.org/show_bug.cgi?id=104398

As I commented in the file, if poppler maintainers want to
decide after seeing how git maintainers deal with this, please
do so. I think this issue is not urgent, except of the people
developing the softwares on Unix with root account.

Sounds reasonable. Maybe easiest and most portable way would be
the extraction of the archive by git once, and add something,
and repack it. But doing such before any requests would be overkill.
