Currently poetry mostly treats python_version x.y as equivalent to python_full_version x.y.0, but is it necessarily so?

#!/usr/bin/env python3

from poetry.core.version.markers import parse_marker

m1 = parse_marker('python_version > "3.6"')
m2 = parse_marker('python_full_version == "3.6.2"')
allowed = m1.constraint.allows(m2.constraint)
print(allowed)

This prints True. But surely PEP508 says that the python_version at 3.6.2 is exactly 3.6, which does not satisfy m1.
