It also flushes the input buffer. I think it is probably reasonable to
let it cancel interactive \if state as well. A useful thought-experiment
is to ask what behavior you'd want if we had metacommand loops ... and
I think the answer there is pretty obvious: you'd want control-C to kill
a loop.
I'm less sure about what it ought to do when control is somewhere in
a script file. I *think* we have things set up to kill execution of
script files altogether, in which case we have the answer a fortiori.
If not, there's room for discussion.
