Yes, there are many workarounds and they work well in the CI usecase. However,
for the arbitrary files usecase there is no good workaround. I currently use
a script which iterates over the tree and renames .git -> dotgit before running
any git command and back again afterwards, but it is slow and brittle. I toyed
with the idea of writing a FUSE filesystem to do the renaming, but it is
needlessly complex and hurts performance.
Really, this problem should be solved in git itself.
