So why don't they have a cable grip on the incomer(s) of a 13a socket?

Because the individual conductors are separated and the whole conductor

The consequences of an aerial cable coming loose are trivial anyway.

Not if it's in a system that's under warranty and is 200 miles away.

Who's going to travel 200 miles to install a TV aerial?
