Are you suggesting that someone should actually write router code to prevent this (i.e., treat site-locals as anything other than regular unicast addresses)?
No. In fact, I am suggesting that all routers and hosts treat site-local unicast addresses exactly like global unicast addresses, and that we administratively restrict the use of site-local unicast addresses to non-globally-connected networks.
If site-locals are used on globally-connected networks, it is necessary for them to be treated specially by the IP stack (address selection rules), DNS resolvers, applications, routing protocols and management software. And, I am suggesting that we do not want to define this usage.
It would be better to produce a "Use of Non-Globally Reachable Unicast Addresses" BCP rather than put meaningless restrictions on address use in the specs.
What would you suggest as the contents of that BCP?
