Because we'd have to invent a new suboperation DISCARD SEQUENCES,
for one thing, in order to be consistent. I'd rather ask why it's
important that we should throw away such state. It doesn't seem to
me to be important enough to justify a new subcommand.
Or, if you'd rather a more direct answer: wanting this sounds like
evidence of bad application design. Why is your app dependent on
getting failures from currval, and isn't there a better way to do it?
