Might make sense to merge this into 29.2?

Thanks for the patch.  I recommend re-sending it to
bug-gnu-emacs@gnu.org so that we don't lose track of it.

Thank you, but the function list-of-strings-p has only been added very 
recently.

project.el is a "core ELPA package", meaning we publish every 
version-tagged release to ELPA as well, maintaining compatibility with 
Emacs 26.1+. So this won't fly just yet.

Maybe in 4-5 years or so.
