Domains vs Domain Aliases... Why?

[pgentoo]

I've been contemplating this for some time, and I really don't understand why we have the concept of a "domain" and a "domain alias". Really all a domain alias is, is another domain that isn't the primary one on the account. So why have different php pages, sql tables, daemon code, etc.... to handle these?

The database already has seperated out the admin user, and the domain. Why not just kill the concept of a domain alias, and allow a user to create multiple domains?

I'm really trying to get converted over to ispcp for my systems, but the whole idea that login to the control panel is based on a domain name, and there can only be one, is a big pain for me. Sure there are domain aliases, but these have their own limitations currently, and i just don't see the point.

Anyone feel the same?

Would it be hard to just kill domain aliases and allow more than one domain to an account? Then we could allow the actual login to manage the domains either be one of the domains (the master?) or some arbitrary username.
