Quoting:
...Despite having been part of the Python standard library for a long time, the asyncore module suffers from fundamental flaws following from an inflexible API that does not stand up to the expectations of a modern asynchronous networking module....
This one is too abstract. You need to mention specific use cases or user stories that asyncore/asynchat fail or this PEP will fail also, just because from all the authors of the PEP you're alone were aware of the problem and forgot about it.
