No.  Providing the security that the user originally asked for is not a 
"backwards incompatible change".  It is a bug fix.  And believe me: I care a 
_LOT_ about reducing barriers to migration.  This would not be on my list of 
the top 1000 things that make migration difficult.

The API already supports both of these things.  What I believe you're 
implicitly saying is that there needs to be a way to do this without editing 
code, and... no, there really doesn't.  Not to mention the fact that you could 
already craft a horrific monkeypatch to allow operators to cause the ssl module 
to malfunction by 'pip install'ing a separate package, which is about as 
supported as this should be.
