Close (and for other projects in this repo, I've thought about doing
just what you propose). Here, the team leader realized that the 1.5
best practice is to merge only from project root, but the team members
are accustomed to 1.4-style merging, which did not have this
restriction. Since they don't really care about the downsides I
mentioned above, they'd rather not retrain to 1.5 best practices.
Hence the question of whether there are any other downsides they
should be aware of.

OT, but since this recommendation comes up a lot, it would be a nice
enhancement if the CAPS argument passed to the start-commit hook gave
the client version.
