There's no room for IPv6 hints. The 512 byte maximum size is full.  
Turning on ENDSO or requiring TCP connections entangles all sorts of
problems with DNS Root Anycast, because those services aren't stateless,
and Anycast isn't reliable with stateful services.

Of course, there really isn't any reason to have the same 13 IPv4
servers handle IPv6 addresses.  A different set of IPv6 root servers
(not anycasted) is what is needed for IPv6 operation.
