Mypy is certainly a prominent consumer, but you're right - PEP 561 type stub
packages are also used by PyCharm, pytype, and I've heard CPython can
use them to compile, to name a few.

So I think my revised opinion is mypy should stay where it is, but I do
like the idea of keeping all the types in one module?

Co-locating them with the module they provide type for also works fine,
but I kinda see the type files as visual noise if we put them in
packages which are organized into categories they don't directly
contribute to. Perhaps they are better kept in once place?

It also means that when running mypy you can just import your
python-types module, and be sure it's going to work.

Cool thanks - leave this with me, I have a working package so can submit
a patch shortly!
