That is true, but I don't see that this means we need a special framework for these features. 2 - I like the idea of being able to list the experimental features. I think NEWS is good enough for that. I think that making a feature experimental is really a matter for us, the developers. If a feature is a self-contained major mode, and certainly won't affect anyone that doesn't enable that mode, that is automatically safe to try installing. So we can just install it with nothing special. But if feature involves adding code in some existing files, files which have other purposes and uses, that added code might break something. So we might want to add an explicit conditional around each piece of code added in other files, so that we KNOW this feature can't break anything if you don't enable it.
