Seems reasonable.  I generally dislike #ifdef clutter, but the #ifs
would only be around a couple of macro definitions AFAICT, so the
readability hit would be minimal.  And someone who wanted
back-compatibility would be able to have it, whichever way we jump
on the decision for 7.3.

At the rate Manfred is going, he'll have patches for all the tuple and
page header related issues before August anyway ... so my original gripe
about wanting to group those changes into a single release will become
moot ;-).  I certainly have no objection to doing them all in 7.3
instead of 7.4 if we can get it done.
