I don't think I said that ICANN should regulate nothing. It is a
regulator (even if it denies it, claiming it only has a "narrow
technical role") so it regulates. But not all regulations are
good. And this one is clearly useless.

I disagree here. The creators of the DNS (thanks to them, by the way,
and congratulations) were quite careful in isolating the
problems. Unlike X.509 (where the weakness of one CA breaks the entire
system), DNS' tree structure ensure that a problem in .nl won't affect
.net and a problem in .info won't be an issue for .jp. There is no
need to be conservative here: both theory (DNS decentralized tree
structure) and practice (the 15 existing TLD with A or MX at the apex)
proves there is nothing to fear for the other TLDs.

The discussion is about TLD, not about whether a A or MX at the root
