Comment on usage restrictions on "dotless" domains.
While the proposed contractual restrictions on the use of MX, A and AAAA records are good, they are likely to be worked around in many protocols by the use of SRV and similar records in the future. For example if SRV support is ever standardised for HTTP then the use of "_http._tcp.example" would introduce the same problems that the restriction on the use of MX, A and AAAA is trying to prevent. Now while one could ban the use of SRV record with a dotless base name, there are non ambiguous uses such as finding whois servers for a TLD, so a careful balance needs to be struck.
