The costs usually come from complexity: every new user needs its credentials, guidance to services and help in error situations. New services need to be integrated to existing systems. But those won't go away, be the system anything.

Sometimes it looks like about anything else would be better as a programming interface.

I have seen no issues in regular subs, and they look like they always have looked.

So I think they can do it pretty accurately.
