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.
