Thanks Maciej. I personally don't have a problem with "experimental" implementations.
We're testing the spec not the implementations, after all, and it's hard to know
for some projects whether a nightly build is experimental or not, but I think I
understand the motivation.

I'm always in favour of not stating things that don't affect the outcome. Does
"implemented for one month" mean no bugs have been found for a month, or that it's
a month since I started working on the feature, or something else? And if I can
just say it was a month ago it doesn't really impose much of a bar and certainly
hard to evaluate as a MUST. I don't think this is a useful addition.
