Ok, so based on your arguments I can see a use case for even/odd values for
page-break, though not really for selectors in the @page rule.

However, I don't think even/odd is a good name for the values, because authors
can manipulate the page numbering. We could call it front/back or verso/recto
(I forget which is which), which would not imply any interaction with page
numbering.
