I don't get it.

If you have conflicting changes, either with SVN or Git, you have to
resolve the conflict manually. Of course it's easy to break the syntax
while doing so, however SVN does not make it any easier than Git.

OK, I now tried this approach with Git 2.23 (see attached log) and
found horrible problems that make it basically unusable:

 1. git-checkout downloads each file in a new SSH connection. It make
the download really slow: less than 1 file per second in my setup.
That means downloading of translations into one language would take
more than an hour.

 2. git-status silently tries to download to whole Git repository.

 3. git-commit tries to download some files one by one again.

The tag [WIP] would hint that we are not sure if it can be
implemented. We can even name it "Reasons why translations cannot
migrate to Git", if necessary.

Agreed.

IMO a Phabricator "task" would be the most appropriate place to
document these answers because we don't have better options: Community
Wiki and Nextcloud are not very suitable for discussions.
