I have no opinion, and it's why I didn't set out to deprecate them at 
all.  The WG consensus wanted this note added, so I think that the WG 
ought to weigh in.

I noted that 260 doesn't accommodate 8-byte ethernet addresses (used in 
802.15.4 today, and apparently a future ethernet spec).

How about:

-IANA is requested to add the note "DEPRECATED in favor of 52 and 54" to 
registrations 260 and 261
+IANA is requested to add the note "DEPRECATED in favor of 52 and 54 for 
IP addresses" to registrations 260 and 261
