I sort of endorse this statement (not really familiar with the 
requirements of a IANA registry, and we should consider feasibility 
w.r.t. current IAUFWG convention registry) ... but yes, there should be 
some univocal recipe (based on one or more keywords, sort of glorified 
"magic" file ... something like this was discussed when talking about 
the establishment of the current registry) to assert that a given FITS 
extension employs these named conventions (I do not see why this shall 
be in the PHDU and apply to the entire FITS file, as some conventions 
may apply only to some extensions).
