when does a "remain clear" instruction end?

No. You posited a lengthy lecture/dissertation that tied up a busy
comm channel.


Right. It was actually the first choice I listed. My mistake.



...neither does "cleared into the Class C airspace", and it has the
benefit of not conveying formal meaning it shouldn't, unlike a
clearance.


Sure it does. To a pilot who mistakenly believes he needs a clearance to
enter US Class C airspace it means he can enter the Class C airspace. "Come
on down" means nothing.



You don't bother explaining how this is a valid clearance.


No, Michael, I didn't explain how this is a valid clearance. That was
because it isn't a valid clearance. What part of; "Yes, I know, there are
no clearances for VFR aircraft through Class C airspace. Nobody knows that
better than I do. But I'm not going to argue with the pilot, if he insists
on a 'clearance' I give him a 'clearance.', did you not understand?



Podunk
approach only needs to say "Waco 9876Z, roger." If Waco 9876Z
can't figure out what to do, he can ask.


And that's what he'll do, ask questions on an already congested frequency.
The reason for simply "clearing" him into Class C airspace was to avoid
adding to the congestion on the frequency.



He might even learn
something. Just issuing a bogus clearance only perpetuates that
ignorance.


Well, you're certainly the expert on perpetuating ignorance.
