My experience is always with a project file; the user explicitly selects
which project file is active. That can be multi-language or
single-language.

So I'm not familiar with the project system trying to guess a project on
the fly, as the current code does.

As you point out, there are use cases for using the major mode to
influence the project, and others for not doing that.

I don't know which would be better as the default; the only general
solution is to require a project file.

Ede also uses the (require 'path/file) style; not surprising, since it
was written by the CEDET team.

I don't see any implementations of ede-source-paths, and only one use of
it, so it's hard to say what the purpose of the mode parameter is.
