Yep. For example, https://pypi.python.org/pypi/python-dateutil/json  ;
https://pypi.python.org/pypi/python-dateutil/1.5/json . This package
does not declare requires_python or use classifiers, and I don't know
whether requires_python would show up there anyway. pip doesn't even
read those json files, but if it did it would be very slow.

pip reads this page: https://pypi.python.org/simple/python-dateutil/
and I suppose also the linked labix homepage.
