In the sense that they allocate /8s (and, in IPv6, /12s) to the RIRs, sure.  I'm just guessing but I don't think the RIRs would be very happy if ICANN/IANA were to refuse to allocate a /8 (or a /12) to an RIR because one of the RIRs' customers was hijacking NXDOMAINs.

Actually, ICANN/IANA assigns these directly (see http://pen.iana.org), but I suspect the folks in the IETF would get a bit distressed if ICANN/IANA started imposing restrictions on who could get PENs.

ICANN/IANA is directly responsible for (and has contractual relationships with folks who operate) gTLDs and has, to the distress of some folks on this list, imposed restrictions on wildcards/synthesis/etc.  ICANN/IANA discourages wildcards/synthesis/etc for ccTLDs, but the operation of a ccTLD is considered a national sovereignty issue and thus, ICANN/IANA has no way to do anything other than point out the problems wildcards/synthesis/etc. can lead to.  As I write this, there are 11 ccTLDs that do wildcards/synthesis/etc. and there will undoubtedly be more in the future. ICANN/IANA has no interaction with, much less control, over ISPs.

Yep.

Government might -- politicians like to be seen solving problems, even if they haven't the slightest idea what the problem is, whether it actually is a problem, or how to go about fixing it.

With the exception of the gTLDs, ICANN/IANA simply can't -- it has no mechanism to do anything other than wag its finger.

There are folks on this list who work for ISPs which are doing wildcards/synthesis/etc.  They (or, more likely their management) can tell you there are obvious business reasons why they do wildcards/synthesis/etc.  Perhaps I'm overly cynical, but I suspect that until those business reasons go away, shining a flash light will probably just result in more ISPs implementing wildcards/synthesis/etc.
