With all these variations, it might be reasonable to consider dumping  
the path macros altogether and switch to a functional model.
The path mapping functions could be supplied by mm_cfg and modified  
as appropriate for the installation.

For example, the existing 2.1 storage is functionally equivalent to:
     def  list_dir ( domain, list_localpart ) {
            return os.path.join( VAR_PREFIX,  'lists',  list_localpart )

Whereas what you're asking for is:
    def  list_dir( domain, list_localpart ){
           leaf = list_localpart
           for dom_part in domain.split('.'):
                leaf = os.path.join( dom_part, leaf )
            return os.path.join( VAR_PREFIX, 'lists', leaf )

And what works for _my systems_ would be:
    def  list_dir( domain, list_localpart ){
           return  os.path.join( '/var/vdomains/', domain, '/mailman/ 
lists', list_localpart)

IF one simply _MUST_ have different mapping regimes for different  
domains....well, then encode it into your mm_cfg.list_dir().
