As explained it does not matter WHAT name fields you use; it is name fields in general. You have to hide ALL name fields (first, middle, last, and name) from registration as well as the username field for username to assume email. However, using incubator project CB Fields you can avoid this all together and set the username to anything you like before or after registration process.

I've created a feature ticket for this to be reviewed for later release of CB as completely agree with you that Email should replace Username even if Name is present. For time being CB Fields can change the username to whatever you like until this could be addressed within CB itself.

OK. Tried the CB Fields incubator plugin, but I can't really test it out because I still cannot complete the registration. The CB Field plugin isn't triggered until AFTER registration (onAfterUserRegistration), so it doesn't help solve the problem of needing to show first & last name fields but using the email address as the username. I tried 'onBeforeUserRegistration' as well.

On before should function as CB Fields alters the user object from reference. At any rate in most cases yes the change is done after registration. Don't understand how this is preventing users from registering however as they'll be given first+last name as username then it will immediately fix after registration.

It looks like my only options are to hide the first & last name fields, or convince my customer to just use usernames and passwords for the login form. I don't see how else to use the email-as-a-username functionality.

Username does not have to be username; you could change it to surname, nickname, alias, etc.. simply by adjusting language strings or changing the field title from field management. That could make it more attractive to your client. Aside from this not much more to suggest until we've addressed the issue within CB, which I can not provide a timeframe for.
