The reason BIP 70 doesn't do this is the assumption that alt coins are ...
well .... alt. They can vary in arbitrary ways from Bitcoin, and so things
in BIP70 that work for Bitcoin may or may not work for other coins.

If your alt coin is close enough to BIP 70 that you can reuse it "as is"
then IMO we should just define a new network string for your alt. network =
"dogecoin-main" or whatever.

You could also use the genesis hash as the network name. That works too.
But it's less clear and would involve lookups to figure out what the
request is for, if you find such a request in the wild. I don't care much
either way.
