The politically correct way to do it would be to create your own
dispatch type. See Catalyst::DispatchType and the built-in dispatch
types (Catalyst::DispatchType::*) for that.

Or, a simpler way to hack it in would be:

sub foo :Chained('/') PathPart('') Args(2) {
    my($self, $c, $prefix, $username) = @_;
    $c->user->check_prefix($prefix) or $c->detach('/error_404');
}

Also, make sure you store the old prefixes and redirect to the new ones
adequately as to not break the web.
