That's not any better. If you have to opt-in to the language as

about this. Imagine spending 2 hours trying to figure out why
your app that is trying out some new feature doesn't compile,
only to find out after posting online that it was looking at
some ancient version of phobos.
You won't have to spend two hours figuring out. If you use a
feature from a later edition, the compiler will give you an error
and tell you what you need to do.
I think it's much more frustrating to pull down a new version of
the compiler and find your current project breaks. You shouldn't
have to change your code or adjust your build system to use a new
version of the compiler. It should just work.
