I want my first check to verify email address uniqueness. If this
validation fails, there's no reason to go further with validating the
user's input. I want a singular message displayed in this case. Is
there a way to do this?
Also, what about group validations, such that, for example, if I have
several checks on a password (existence, complexity, confirmation) and
one fails, the others are ignored. So for instance, if the password
field does not match its confirmation, I skip validating the password
complexity.

I think the best way would be to use your own function (instead of
error_messages_for) for displaying the error. You might also be able
to get somewhere with the :if option to validations (and have your if
function check whether there are any errors yet). While the examples
you provide are interesting, more generally it is really annoying as a
user to have to correct form errors once at a time.
I'm still not sure how I'll approach this. I'm going to spend a bit
of time tinkering with the :if option, as well as creating my own
validation function. I agree that it is annoying for the user to have
to correct errors one at a time. But I'd imagine correcting a series
of errors, just to finally realize that the email address has already
been registered, might be equally as annoying. Hence why I want the
email uniqueness check to be first and foremost. If their email
address has been used, the rest of the validation errors become moot.
