I think this could be marked experimental in v5.36 and, most likely, not experimental in v5.38.  It would be okay, and I wouldn't object.

That said, I'll point out that "experimental" warnings are there because they might *change*, and not because they might have bugs.  I don't believe we're likely to make incompatible changes with the syntax proposed, but I also think that one experimental version is a reasonable position to take.  In general, though, I'd rather we just say "This feature is new and while we've tested it enough to feel good, it may have bugs not caught until it gets executed a few billion times."
