So the logic is something I posted to this thread already:

    So, a few things.  First, these set of commits was in a group of 10 that
    I added since there have been complaints in the past that optimizer
    improvements were not listed and therefore patch authors were not given
    sufficient credit.  That means the 209 item count for PG 18 is 10 higher
    than my normal filtering would produce.
    
    Second, looking at the items, these are a case of "X is faster", which
    we don't normally mention in the release notes.  We normally mention
    "faster" when it is so much faster that use cases which were not
    possible before might be possible now, so it is recommended to retest.
    That is what I saw this grouped item as, whereas I don't think the
    individual items meet that criteria.

So, users are interested in performance in the sense it makes use cases
possible, and if your commit is making the case folding useful, we
should mention it in the release notes.  I don't think making it
separate would fit though.

  Do not let urgent matters crowd out time for investment in the future.
