Yes it does. It just supports it badly. If there is a work-tree connected to
the receiving repository and that work-tree is pristine, it would be safe and
sane to write the newly pushed changes to the connected working tree.

We do all our integration fixups by pushing to repositories with work-trees,
simply because it's ridiculously inconvenient to add the infrastructure to
pull to those repos from each individual developer. In that scenario, pushing
to a checked out branch is highly useful and perfectly safe.
