5 versions for a series like this one was to be expected. Imo it has
been wrong in the past to rush in new features (even if experimental
ones) very close to the freeze, and it has mislead people to think
they can delay work until very (too?) late a point in time.
In fact I'm getting somewhat angry seeing how much effort is put into
getting this work in (including myself doing reviews there), when at
the same time far older series of mine aren't given any chance to
make any progress. Not your fault, sure, but an observation.
