Because I disagree with your proposed fix and overall judgement of the problem
but don't want to argue about it in context of this issue.

Finding a way to put a deprecation stage into this stage is something I keep
thinking about.

It is more intrusive change (will fail in more context) and I think that
getting address of a method as a delegate is perfectly legitimate code - it
would allow to set `dg.ptr` manually later to call it with arbitrary context.
