[acm] 
Sure. 
It's equally striking to me that this terminology overload 
wasn't flagged in the original development of RFC 2330 (where the
notion of a class C of packets was first introduced, 20 years ago)
https://tools.ietf.org/html/rfc2330#page-19
or when we developed the definition further in RFC 7799, end of section 3.8
https://tools.ietf.org/html/rfc7799#page-8
(much more recently). 
And again on the topic of route metrics in
https://tools.ietf.org/html/draft-ietf-ippm-route-01#section-3.5
last paragraph.  I'll add the clarifying phrases before this memo
reaches IESG.

[acm] 
Thanks for catching that. "minimal IP packet" is the correct term from
RFC2330, and we'll update the abstract.

[acm] OK  ,proposes
;-)

[acm] easy to fix now since we're pushing changes,
and reduce the Q/A with RFC Editors.

thanks again,
