If we just tell them that the thing they might have relied on might go away, without a replacement to suggest, then we're just confusing and scaring them, no?
We'd end up suggesting our OFFSET 0 hack as true protection. If they know for a fact that their use of CTE for its barrier properties is not supported they are also more likely to document intentional usage with something like: "-- CHANGE THIS ONCE VERSION 11 IS RELEASED!!! --" which would make finding the call sites that need to add the new "MATERIALIZED" keyword much easier.
