Why is this proposal special in that respect? This is not an IETF requirement
and despite the BCP advocating an Implementation Status section, very few drafts
do this.

Note, I am all for some trial implementations, but why does *this* draft
need one when so many others don't?

Well, both are needed for a real test (plus a demonstration that legacy
stacks ignore the flag). Personally I don't have the Linux smarts to do
this, but of course it would be great if somebody volunteers.
