I agree with you, letting more time for accepting more specs means less
time for merging more spec implementations.

That still leaves 6 weeks for accepting around 80 specs, which seems to
me enough.

Looks good to me too. Proposing and advertising one review sprint day
(or even two days) around pike-2 could also help us, because we could
have this kind of 'runway' between proposers and reviewers.

If so, after pike-2, we could just see how many blueprints are left for
the last milestone which could help us having a better vision on what we
could realistically feature for Pike.
