yes.

Yes, they're clearly arbitrary, and yet agreement is
critical to interoperability, and syntax engineering is
a big part of what makes the web go around, apparently.

Technically, one character names would suffice and would
save bytes on the wire. But short words seem reasonable.
multiple-word-names seem like overkill.

There were some "what if we had stuck to just one
or two characters for HTTP header field names?" studies
that left a lasting impression on me. Hunting thru
the archives, I find this in a draft from Mogul & Leach
in July 1997...

[[[
5.2 Abbreviations for Meter directives
   To allow for the most efficient possible encoding of Meter headers,
   we define abbreviated forms of all Meter directives.  These are
   exactly semantically equivalent to their non-abbreviated
   counterparts.  All systems implementing the Meter header MUST
   implement both the abbreviated and non-abbreviated forms.
   Implementations SHOULD use the abbreviated forms in normal use.

...

       abb-meter-request-directive =
                         "w"           ; "will-report-and-limit"
                       | "x"           ; "wont-report"
                       | "y"           ; "wont-limit"

That seems like more complexity than I'm interested in.
