He's claiming your solution to address your use case is confusing, not
that the use case is invalid.

I'm not going to make ipaddr less useful (strictly removing functionality), more bulky and confusing (adding more confusingly named classes and methods) or otherwise break the library in a vain attempt to have it included in the stdlib.

If I understand correctly, the proposal for addressing the issue is to
make two rather simple changes:

  1. if strict=False, mask off the bits described by the netmask when
    creating an IPNetwork, such that the host bits are always 0.
  2. add a single new function:

def parse_net_and_addr(s): return (IPNetwork(s), IPAddress(s.split('/')[0]))
