Varnish will almost certainly implement whatever comes out of this.

Notes from our mumblings in the project:

The "Very Large Value" solution it is brittle in more ways than is
desirable, but try as we may, we don't see any simpler/better ways
of doing it without negotiation/hints.

We suggest to either put a "Quite Large" lower limit on "Very Large
Value", or better yet:  Make it a magic value large enough to not
be a problem relative to actual Range requests.  If we keep with
the 9's motif from the draft, we suggest 999999999999999999 which
doesn't needlessly provoke 64-bit sign issues.

Typo on page 3: "accessable"

Never attribute to malice what can adequately be explained by incompetence.
