Reacting on the "when to implement" part of the subject, and speaking
for NLnet Labs.

I think there is a sweet point when developers start to think of
implementing a draft.  Not necessarily WGLC, but a stable document is
preferred with us at NLnet Labs.  (We indicated this also on the mic in
the Prague DNSOP WG meeting (or Singapore?) for the kskroll-sentinel draft.)

As Ralph Dolmans mentioned in his email on the list (specifically for
the kskroll-sentinel draft):
"We need a somewhat stable specification before we make code that will
be used in the real world to prevent pollution and in this case would
make it even harder to do proper measurements."

Above is specific for the kskroll-sentinel draft of course, and for
other drafts this point for adoption to get a (prototype) implementation
can be earlier or later.
