I think it's easy to miss/enforce a documented policy. IMV, moving
towards pg_attribute_deprecated as Alvaro Herrera said in the other
thread https://www.postgresql.org/message-id/202311141920.edtj56saukiv%40alvherre.pgsql
can help. Authors then can declare the variables and functions as
deprecated so that the code compilation with
-Wno-deprecated-declarations can help track all such deprecated code.
Having said that, I'm all +1 if the v1 patch proposed in this thread gets in.
