It does... but the original design for GFAL2 didn't, as the LFC was
supposed to be phased out initially! There's still a feeling from the GFAL2
guys that they don't really *want* it to support the LFC.

I can't think of a way to force things other than what's already been tried
- there's been concerted efforts to get people to stop using the LFCs, but
there's never been a will to force them (and, as I noted, there's even new
experiments choosing LFC over other technologies explicitly).
