Committers have always added features after freeze...
For example, Virtual TransactionIds were added to 8.3 almost exactly 5
months after feature freeze. Not even suggested until about 5 months
after, in fact. I argued against such a change late in the cycle, but we
did it. It's a great feature and I'm glad we did.
If we try to shorten the release cycle, we just end up missing out on
tuning opportunities that emerge in beta. IIRC 8.2 was delayed while we
changed index cost models. Thankfully.
8.0 was shipped with a completely ineffective bgwriter, so the above
changes seem like common sense in comparison.
The only way to keep the dev window open longer is to overlap the start
of the next cycle with the previous one. i.e. branch new version before
final release.
