Yes. Please ship it under /usr/lib/tmpfiles.d, and give it a clear prefix that identifies the package (eg: tmux-something.conf). Also please understand that any user can define any cleanup rule they want locally, and they will override what packages ship (this is by design), so the flock solution would be safer.

Yes understood, that is something appropriate to do upstream and not downstream, I agree. I'd suggest to mention 'screen' as a factual example for this pattern, it might help.
