Not you alone.  It's a long series of small changes, each one of them
considered "important".  Together they add up.  And then COVID-19
added its toll.

Someone, somehow, you name it.

There's always "that one last" issue to be fixed.

The only way to speed up our releases that I see is to care less about
stability and regressions.  If you are following the bug list closely,
you will see that we just recently started to get reports about
significant regressions in Emacs 27 (and some in Emacs 26).  Should we
disregard them?  We never did that, not since Emacs 25, at least.
