Maybe when road frames start getting direct mount front dérailleurs.

Mainly that a lot of the TT bikes which are losing their front dérailleurs have weird shaped seat tubes and road-type dérailleur hangers, so clamping to the seat tube is impractical but there's a handy mount to bolt the chain guide to if only the chain guide had the right kind of interface.
