I don't think I agree.  I've never published a book, but were I to do
so, I think it would be more intuitive to think of the pages in terms
of left/right rather than even/odd.  The latter requires me to
remember exactly which side page 1 starts on - in other words, I'd
just have to use some extra knowledge to map the even/odd back to

Is there a common pattern for which side page 1 starts on?  I've read
thousands of books in my life and never really noticed which side was
even and which was odd.  Is this pattern the same for ltr books and
rtl books?

Are you expecting that authors (or perhaps publishing houses) will use
a single common stylesheet for both directions of books?  If there was
a common pattern, and it was shared between both book
directionalities, this still wouldn't help any individual book, as
books are always published with a particular directionality.  You'd
only realize a minor benefit if you're publishing multiple books in
both directions, and have a common base stylesheet that you use for
all of them.
