Meh.  There may be many new TLDs, but they are looking rather empty and
insignificant.  We'll see how it goes for them, but I'm betting on
'badly'.  In any case: it doesn't matter.  What matters isn't how many
of these there are, but that the number of unconstrained CAs be low
(which DNS achieves, while the WebPKI does not).
