Ah thanks, I get it and know where to look now!
I've added another example using Okular 23.02.4 (with/against Poppler 23.06.0),
and that noticeably keeps a stable file size also when adding multiple
annotations. It is somewhat smaller than the Okular 22.12.3/Poppler
23.06.0/built against Poppler 23.01.0 sample, the difference seems to be down
to Okular 23 only embedding Noto Sans, not Noto Sans and Noto Sans Regular
both.
So - for my purposes - Poppler 23.06.0 and possibly Okular 23.02.4 are the
required combination for a PDF annotation workflow without... "file size and
performance surprises."
