I need to ponder this with a nice bottle of wine this evening...maybe.

My gut feeling is that, by pure numbers, most users want Apache to
serve domains one next to the other. They do not want overlaps, they
want http: and https: for the same domain to show the same resource (or
have the former redirect to the later).

I think they would like Apache to refuse a configuration where this
is not somehow true (e.g. ServerAlias/Name overlapping, a Location
slipped into one vhost of a domain, but not the other). The would
like Apache to answer 404 for any domain that is not configured.

Then we have fewer, but possibly larger and "more interesting" setups
where people use the config possibilities up to the max, know which
virtual host a fallback for unknown domains is, etc. etc. etc.

How far would come in satisfying all by having a core directive

   DomainScope          global | ports | sockets | free

with meaning:
free:    as is now
sockets: domain settings are unique for each address+port (can be same for 
different addresses),
         e.g. ServerName/-Alias props can differ on each listening socket
ports:   domain settings are unique for each port number (irregardless of 
listening address)
         e.g. ServerName/-Alias props can differ on other ports
global:  domain settings are unique for all ports and addresses, 
         e.g. ServerName/-Alias props are the same everywhere in this server
