I think watching files makes sense for FrankenPHP's use case of development server, but I can't imagine the overhead and non-portability makes sense for the stat cache. I feel any gains you'd have from stat cache would be offset by that. And it'd be unfortunately the only way to actually solve the "external thing changes thing behind the stat cache's back" problem.
