I can understand, that at some point, language features will become too important to retain compatibility, but this looks dubious to me.

It was a suggestion, so Kevin can choose not to change it.

Formally, OpenJFX N supports JDK N-1, so for 17 we should be able to use features from 16. It was decided a while back not to force-fail on older JDK versions and let it evolve naturally.

While in this case the change is small and might not be worth it alone, many of the recent language changes are geared towards better readability and reduction of possible mistakes, and we will be hurting ourselves in the long run if we don't pick those up. Every PR is relatively small and doesn't require the new features it can take advantage of, but if we go this way then we will be stuck with JDK 11 until something like Valhalla comes out.
