From that perspective, moving to OpenBSD seems mostly pointless as currently the best practice there if file permissions are too strict seems to be "comment out some unveil lines and recompile the program." Not really an improvement IMO.

From that angle if the permission dialogs bothered you then you could just recompile flatpak to unconditionally approve all dialogs. (Maybe there is even a setting for this already?) Of course as a sibling comment has said, this would be pretty dangerous, almost equivalent to using windows without UAC, or sudo with NOPASSWD.
