Straightforward for what? Use againframes? Or force label?

Force label. Having to explicitly state it twice :

* Frame 1

:PROPERTIES:
:CUSTOM_ID: foo

:BEAMER_opt: label=foo
:END:

is not exactly straightforward. The following (crude) patch would avoid it.

Anyway, the BEAMER_opt label= way of setting the label is not Org-y.
