If they're still experimental then they shouldn't be enabled by default for non-Apple ports. (This doesn't affect Apple ports as those ports disable experimental features in stable branches instead.)

I’m guessing viewport-fit doesn’t affect non-Apple ports… do you support <meta name=“viewport”>?

I would say it’s probably reasonable to move viewport-fit to the non-experimental features section, and turn constant properties off for other ports (they’re still experimental/in-flux).
