That raises the question, though, if we need to further categorize by
including session layer attacks and presentation layer attacks, or
should continue to lump these into application layer attacks.

Isn't Cross Site Scripting and Session Hijacking/Riding not a session
layer attack? Is the recent International Domain Name issue (raised by
the fine folks at Shmoo) not a presentation layer attack?
