First off, I still feel that there was a consensus last year on using the
network tag for distinct network subsets as well as for mainline roads and
you, despite being the only dissenter, continue to argue against something
the rest of community more or less settled on.

Secondly, I think this highlights a reason to use network subsets in the
network tag: because it's a simpler rule to apply than deciding whether a
variant route is different enough to deserve its own network value.  You
seem to have a clear idea about what constitutes a network from your
perspective--Interstate 75 Alternate and Downtown Interstates do, but
Interstate 270 Spur doesn't.  I think there's a lot of grey area where
people with different perspectives would disagree[0], especially mappers
who just want to represent what they see on the signs where they live
without arguing the minutiae of which road network a route is really a
member of.

In short, you seem to want to have the final say about what is or isn't a
"real" network, but OpenStreetMap is a community effort and not only does
the "network tag can have distinct values for network subsets" scheme
appear to have broader community support, but it also seems to me to be
the most generally applicable by people who in all likelihood will have
different opinions about what *really* constitutes a distinct road
network.


[0] I feel, for instance, that I could make a convincing argument either
    way as to whether Texas's loop roads should count as their own network
    or should be part of the state's main network.  Likewise for routes
    signed as US 1, US 1A, and US 1 Alternate.
