Depends on the use case. I have several worktrees that are nominally in
several projects; they are utility libraries, so they can be accessed
via any project that uses them, and they also have test suites, so they
have a project of their own.

There is no way to identify the current client project from a utility
library buffer, so I rely on a global setting.

In addition, it is the act of selecting each project the first time that
sets the appropriate environment variable (in this case, giving the
path containing the appropriate versions of utility libraries).

That makes sense. ada-mode projects support that, but I haven't had the
need for a project level generic function yet.

Right. That mode should certainly be supported.

Yes.

Ok. Since env-project is somewhat controversial, I'll just include that
in the ada-mode elpa project for now; we can split it out later if that
seems useful.
