And/or adding new custom variables and hooks.

As explained in the other email, it's a matter of interpretation.

find-file-hook seems a bit late to use if we wanted to save which 
project the current command was called from.

project-find-file would only affect file-visiting buffers, and only ones 
that we already consider a part of the current project. So what new info 
would it save?

"Some other feature" sounds nice.

I'm still not certain of what is the optimal solution.
