Nothing yet abstracts out the username from the userid (although this
is now documented in the Zope Interfaces wiki so it is comming).
You can achieve the functionality you want by writing a plugin for
LoginManager, or modifying UserDB or the GenericUserFolder.
UserDB might do what you are after out of the box actually - I'm not
sure. These products are all available on www.zope.org.

LoginManager's GenericUserSource and the GenericUserFolder would
both require username->userid lookups in your situation whenever 
you access a user objects attributes (eg. retrieve a list of roles). 
However, if you are doing this via a ZSQL method this is a fairly 
insignificant overhead if you remember to use the ZSQL methods cache 
settings thus saving RDBMS lookups.
