I don't really see what the confusion is about. It's for features that we
have all agreed to include, but that the public API or behavior might
change in minor versions while usage information, feedback, and so-on
happens. The idea behind an experimental inclusion would be something like
"the concept behind this feature we've agreed to include, unless something
truly drastic comes up once it's out in the wild, but the syntax,
parameters, and signatures might change while we look at usage and
real-world code.

It's like the opposite of a Deprecation notice in my mind... it's a flag on
specific code that lets people know *ahead of time* that BC breaks in a
minor version might be necessary for this feature for a little while.
