Can I suggest that, as it is so easy to add an option to an individual
frame [1], that it's better for this to be under direct user control?
I don't want framebreaks unless I've asked for them.  In any case, it
would be difficult to ascertain, from the org text directly, whether
the code is actually going to be part of the slide.  E.g. I use a lot
of babel in my slides and, more often than not, I don't export the
code, just the results.

cheers,

[1]   key sequence "C-c C-x p envarg TAB [allowframebreaks] RET"
which you could obviously add to a single keystroke, via fset say
