 Sort of off topic but: I see versioned feature bundles as sort of a middle
ground between optional features and compatibility breakage. It still
requires opting in, *but* it is an opt in that we want many people to
decide to do and has many varied effects, and when possible make it easy to
apply to existing code. This was one of my arguments for changing feature
bundles to 'v7', 'v8' etc to make it easier to remember what you're
getting, but as of yet that doesn't really fit into how Perl is developed.
