Comment (by flixos90):

 I personally think this would be a great addition to WordPress Core. While
 Gutenberg's implementation is only an experiment and therefore not quite
 running at scale, output buffers are and have been heavily used by various
 popular products (e.g. full page caching plugins) for more than a decade.

 That said, while it's a technically simple change to make and clearly has
 large benefits, it hasn't been in WordPress Core all these years although
 it could have - so the question is why. Are there any real concerns, or
 has just nobody been confident enough to push for adding it so far?

 With those questions in mind, I think this should get signed off from at
 least a few seasoned committers. So it may be a bit too late at this point
 in the 6.8 cycle, with just 5 days left before Beta. We can still see if
 we can get such consensus quickly, but worth flagging the timeline.
