In section 5.2.4.1. Subpacket Hints:

Both PGP and GnuPG put the creation time in the hashed area, and the
issuer in the unhashed area, and the most recent draft was revised to
match this reality.  Given that, perhaps it would be good to modify
the phrase slightly with "... as the first subpackets in their
respective subpacket lists..."

Just so I understand... given that a valid OpenPGP message can have 
these packets anywhere in the list, how is it easier for a conformant 
implementation to find them? Faster... now that I could understand. But 
it would seem that any valid OpenPGP implementation will have to 
implement the complete locating algorithm anyway. What is it that I'm 
missing?

I've always interpreted "easier" as "faster" in that sentence.
