"." is not special as far as version numbers are concerned. It's not
a separator, for instance, and "1." is a valid version number (which
is equal to "1.0").
We need a total ordering of version strings, and any approach is
arbitrary to some degree because we don't want to use purely
lexicographic comparison (otherwise, "9.x" would be greater than
"10.x", which is clearly counterintuitive). There are upstream
version number schemes for which the Policy algorithm works perfectly
well (1.01, 1.02, ..., 1.09, 1.10, ...) and others where it doesn't.
