Of course it would be nice to have a consistent behaviour for clef, time 
signature, key signature. But note that those three entities are 
conceptually different in that clef / key signature are per-staff while 
the time signature is (usually) per-score.

I've been wondering for a while now if "forcing a clef" should really be 
done via a one-time-only context property. Wouldn't it make more sense 
to control this in a persistent setting (a context property in Timing or 
Staff, respectively) that controls whether a "\clef XX" gets discarded 
if the previous clef already was XX? So the behaviour with respect to 
"redundant" \clef, \key or \time commands could be controlled in \layout 
{ } ?
