In theory, files on different hosts could be part of the same "project"
(in Eli's sense, see
https://lists.gnu.org/archive/html/emacs-devel/2020-07/msg00051.html and
the other messages in that thread), but we'll get there when we get
there. Probably by adding a method like project-contains-file-p.
In the meantime (until somebody complains), the patch like this should
be fine. I haven't found any significant difference in performance, but
I don't have Tramp buffers in the current session.
Pushed to master, thanks.
If we do believe that a project can only span one host, we could also
change the check like this:
diff --git a/lisp/progmodes/project.el b/lisp/progmodes/project.el
index 33827136a1..6f911e4fbe 100644
--- a/lisp/progmodes/project.el

WDYT?
