I don't know what's the best course of action in each case, but if we 
did make a point of releasing more often (e.g. did time-based releases, 
for instance), Emacs 27.1 would probably have been less stable. But it 
would have been released maybe a year ago, and by now we'd already have 
released, say, 27.2 and 27.3, with more regressions fixed and faster 
because of exposure to a wider audience, more testing.

It's a tricky road, but a possible one.
