Xintong Song commented on FLINK-32978:
--------------------------------------

Thanks for reporting this, [~Sergey Nuyanzin].

You're right, this is indeed a problem.

I think the interface change itself is non-breaking. The problem is that we 
also migrated the built-in implementations from the old interface to the new 
one. That should be fine for internal classes, but would become a breaking 
change for @Public / @PublicEvolving classes which might be overridden by user 
codes.

[~Wencong Liu], could you please look into this?
