This time , I'm the one who is puzzled:
what is the point in naming the link "foo" and getting sec:orgheadline1
instead? :-)

If you add :BEAMER_OPT: label=foo
to the properties of the first frame, then you get the foo label.
But that doesn't seem very obvious to me. Why not taking directly the
CUSTOM_ID label ?
