Review Comment:
   What I mean is that users that are up to date will see this warning because 
their version is going to be more recent than 2.6.
   
   I'd like them to see this warning if it's their code calling the function 
(unlikely, but I understood that we cannot just remove a function before 
warning before) ; but NOT if it's called in an operator they are using, because 
then they cannot do anything about it.
