If serializing access wastes less time than conflicting concurrent work,
this would be appropriate.

There might be more convenient ways to communicate your intent - like
saying so ahead of time in an email or group meeting/call, but if not,
this seems like the right way to let others know that work on these
files must be serialized for some duration and keep them from wasting
their time. And if you are doing this piecemeal, remember that someone
else could be making their conflicting changes in the opposite order and
never run into your locks.

Branching doesn't really avoid the problem with wasted concurrent work
that can't be merged - it just isolates it for a while.

A lock is an enforcement mechanism, not a declaration of intent. Using
it that way would be like finding out your spouse isn't happy by
noticing that the locks have been changed on your house.
