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

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

[Sean Feng [:sefeng]]

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

(In reply to Ben McCann from comment #10)

When will this be enabled by default in release?

Looks like it's enabled by default in release as of bug 1626997 (which landed in version 86, currently beta and hitting release next week I believe).
