The doc is, well, missing.
Nothing for the advice of `redisplay-(un)highlight-region-function' or
`region-extract-function', or for those variable themselves, or for the
functions used to advise them (`rectangle--highlight-for-redisplay', for
example).
Nothing for `redisplay--update-region-highlight(s)', or other funtions
that use those `*-function' vars, or for `pre-redisplay-function', which
uses `redisplay--update-region-highlight'.
IOW, nothing for anything that does region (un)highlighting redisplay,
including `deactivate-mark' (which has a doc string, but whose doc
string does not cover this new part of its behavior).
None of the so-called "New rectangle integration with kill-ring"
behavior is documented in doc strings. It is also not documented in
NEWS, AFAICT.
This code change represents a change in user-visible behavior, and it
should be documented.
[It's a shame that Emacs Dev has increasingly neglected to add helpful
doc strings (IMHO). The originator of the self-documenting editor is
no longer watching closely, and developers will be developers, I
suppose... Too bad.
BTW, why is Emacs code simply using `add-function' all over the place
now, instead of actually adding the code to the functions? Is advice
the new normal for Emacs code maintenance?]

Having a doc string on, say, `rectangle--extract-region' to say "extract
the region, but in a rectangular way" doesn't really seem to say more
than the function name itself, so I don't think that'd be helpful.
Closing.
