pip's UX decisions aren't likely to ever be put through the PEP process
again - the PEP 426 (and now PEP 470) model of providing functional
requirements and recommendations in the form of MUST and SHOULD statements
is a cleaner process, since they provide guidance for all clients, not just
pip, and leave the *details* of the UX to the normal pip development cycle
(so if user feedback indicates a problem with the specifics of the initial
approach, they can address that while remaining compliant with the
Decoupling functional specifications from UX details of individual tools is
a good idea in general, this is just applying that model to pip and the PEP
process in particular.
PyPI needs to be covered in more detail, however, as these PEPs also serve
as the *interface* specification for both clients and servers, and those
need concrete API definitions to work with.
PEP 438 was the main case so far where the PEP included specific UX design
details for pip, and that's the aspect that *won't* be repeated.
