is this necessary?  are all these projects known to work with 3.2, without 
having changes compared to 3.1 *without* this pep?  hardly ...

how many extensions will use this restricted api at all?  Is it a legitimate 
solution to back up building an extension in the "default" mode?

even without having any changes in distutils it would make sense to know if an 
extension can be built with the restricted ABI, so maybe it is better to defer 
any changes to the extension soname, and provide a check for an extension if it 
conforms to the restricted ABI, even if the extension still uses the python 
version specific soname.

I did not mean to block this pep by choosing any installation names.
