Is there any good reason to support multiple queries separated by ;? Is
that for atomicity? If there's no good reason then this seems to be
complicating the API unnecessarily.

You can't know what a user will enter in a console for example, and
returning accurate information in case he/she enters several queries
is a necessity.

Usually people do know what's in a command and this is why it's better
to use the alternate functions I mentioned before; this API is simple

That's also something worth mentioning explicitly in the documentation.
