For preview one the branding is:
new thing = UseGlobalRouting/UseEndpoint
old thing = UseRouter
We're going to drop the name Dispatcher everywhere and make sure that we
position our new work as 'new and improved routing' instead of
introducing a new product/concept name.
We're not totally sure of the term Global yet, but it's what we're doing
for preview 1. Suggestions welcome for dicussion after we do the first
preview :)
