If you *are* willing to do the work, the chances would still be
pretty slim. Guido has just rejected a patch adding PEP 8 compliant
aliases for types like datetime […] As Guido has quoted before, "A
foolish consistency is the hobgoblin of little minds".
Indeed, that quote is prominent in PEP 8 itself.

Not that I can't live without, but I am just wondering why they did
not [name built-in types consistently with other classes] in the
first place?
Because, in the first place, built-in types were disjoint from
user-defined classes. The latter could not derive from the former, and
it was helpful to know the difference.
The reason no longer exists (since built-in types and user types are
now in a unified hierarchy), but the difference is well entrenched now
and I personally see little benefit in changing it.
