That's exactly the point. We have 'experimental' code that's been marked as such for 10-15 years. Maturity has nothing to do with that option, even if that was its original intention.
The reality seems to be that near everyone sets EXPERIMENTAL because there's so much stuff tucked behind it, that they want at least some of it. They aren't choosing this option because they care about how mature the code is, they're setting it because they *need* something that it's hidden behind.
What *might* be a more useful thing, is instead of adding new options depending on EXPERIMENTAL, introduce something like CONFIG_NEW_IN_3_6 (and a release or so later, when it's not considered new any more, drop it). But I'm not convinced that even this wouldn't succumb to the same neglect that EXPERIMENTAL has.
