@martinthomson 
> I realize that you could change the meaning of disable_active_migration to apply to the address the server uses in the handshake, but there are interesting corner cases and I don't think we need to concern ourselves with those. For instance, if you connect over V4 and get disable_active_migration and server_preferred_address. If that SPA includes a V6 address you can't use, along with the same V4 address, what then? Does the server really support migration?

If this example is concerning, I'd argue that is an issue that already exists, orthogonal to what we are discussing here. I am still not convinced that limiting the scope of disable_active_migration to just the original address is going to cause any _new_ issue.

That said, if nobody needs this change, I'm more than happy to move on with status-quo.
