Add standardized prefixed APIs as separate entries?

Honestly, I do not love the change in https://github.com/mdn/browser-compat-data/pull/22951. It seems to me that spec'd prefixes ought to be their own keys in BCD (i.e., we ought to have both css.properties.-webkit-line-clamp and css.properties.line-clamp), since in a lot of ways it's more like a shorthand than a prefix.

Should we do this?

In my opinion it should be separate as the implementation is quite different. At the very least, maybe a subfeature for using line-clamp outside the limited context in which -webkit-line-clamp is applicable right now? Chromium is currently working on implementing this feature and it may end up in Interop 2026, so it should probably be considered sooner rather than later.
