"pipenv check" fails with latest build instructions

  playing with quentin's latest pipenv instructions, and noticed:

$ pipenv check
Checking PEP 508 requirements...
Specifier python_version does not match 3 (3.13).
Failed!
$

since, as i read it, "python_version" in Pipfile cannot just be "3",
but needs to be at least a major release like "3.13". other than that,
sphinx-lint and stylecheck seem to work fine, so do we even care?
