Does it mean that when PHP 8.0 comes out (in roughly two years' time most
probably), we'd be saying this is experimental?  Or that only in the
meantime, for the brave folks that want to experiment PHP 8.0 ~2yrs before
it's released, we'd say it's experimental but will remove that tag by the
time 8.0 is released?

If it's the former - I don't think we should go in this direction.  If we
decide that it's sensible to have it - I think we should work to ensure
that it's production ready by the time PHP 8.0 is released.  Offering it as
something experimental (i.e. not for production) in 7.4 can help us with
that goal, as it will make it easier for a wider range of people to
experiment with it and provide feedback.  I can't think of any
technological downsides to including it as experimental in 7.4 - there's a
slight "marketing" downside (it will be less of a shiny new thing in PHP
8.0), but personally I think the feedback we're likely to get is worth it.
