I don't see why, since it only acts as a default.  Any registrant that 
cares which CA they use can publish their own CAA.  If the registrants 
object, that's between them and Afnic.

Over in DMARC land we have a proposal called PSD which specifically sets 
a default policy for the whole TLD, since .BANK and .INSURANCE want to do 
that for their registrants.
