Under Jesse’s new plan for 5.16+, it would make sense for ‘use v5.14’ to turn off any 5.16 features.

       use v5.16;
       # ... brand spanking new features enabled here ...
           use v5.14;
           # ... only ‘fairly’ new features here ...
   # ... Classic ...

But should this be implemented in (so ‘use feature ':5.14'’ disables 5.16 features) or pp_require?

To me it makes sense to have feature bundles as simple lists of features and make ‘use v5.14’ do an implicit ‘no feature ":5.16"; use feature ":5.14"’.
