It works for constref if you use {$VARPROPSETTER ON}.

The docs for that directive are slightly incorrect, I just noticed, also:

https://www.freepascal.org/docs-html/current/prog/progsu121.html
Where it says "Enable use of var/out/const parameters for property
setters", it should say "Enable use of var/out/constref parameters for
property setters", because "const" is always allowed, and does not
*guarantee* by-reference passing the way "constref" does.
