I've added a note to our experimental features page, clarifying the support status of this:

https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Experimental_features#HTML

We don't normally release note things that aren't riding to release.

FWIW, looks like this pref is making some good improvements, bug 1647646 has more info.

When will this be enabled by default in release?
