Crystal is sponsored by https://manas.tech/ and the company actively provides paid support to a number of commercial clients. Breaking changes have been really low lately. I have a couple of shards that work on 1.0 as well as they did on 0.27 or so (that's 10 major dev releases ago). And with 1.0 there is a guarantee to not have breaking changes until 2.0. I don't agree to the other points too, but that's more subjective.
