Works for me.

This will not always DWIM.  For example, it could be that a buffer
belongs to none of the projects known to Emacs, in which case Emacs
should somehow fall back to "the last used project", whatever that
means.  A case in point is when I compose mail about some problem I
have working on a project.

Second, sometimes I go to another buffer temporarily, for whatever
reasons, like to see how a certain problem was solved there.  But I
still am working on the same project I was before I switched buffers,
not on that other buffer's project.

So there should be a way to tell Emacs about these use cases,
otherwise the feature will still annoy.  I don't see how automatic
inference based on the current buffer can cater to those use cases.

IOW, I think there should be support for "I only work on one project
at a time" kind of users, which means "don't switch projects on me
unless I approve".
