The PEP title does say version *numbers* (plural), and that seems more general
than using 'strings' here.

I'm not certain that the additional story informs any recommendations made by
the PEP. In the case where the version number is kept in some external file,
then you'd likely see something like this in setup.py:
setup(version=open('version.txt').read())
or this in foo/__init__.py:
__version__ = open('version.txt').read()
The details aren't that important, but the fact that the version is kept
in an external file doesn't change any of the recommendations the PEP is
already making.
