I think, yes. Do you assume it can't be? Ha-ha. Rails has many errors (see issues), some of them potential (not noticed or not important for now). It's OK, but we can do it better. Rails is not a standard for Ruby (especially out of web).

If you can argue with something except "some gem has this too", but with something truly about Ruby and the subject — please, do.

See the 2019 ruby conf and matz presentation about backward compatibilty. It should br sufficient.

Ruby 3.0 (?)

So, there were plans for Ruby 2.7 but unknown changes for Ruby 3.0. Because it's unknown feature, and even some changes become reverted before releases.
