I don't see this happening.

An engine warning is as stark a mechanism as we have available that you 
either made a mistake, or shouldn't be doing something, without 
preventing you from actually doing it.

It may be that in 8.2 if this RFC passes that message will change to 
include "This will throw an error in PHP 9", but giving multiple 
messages for it is not beneficial IMO.
