I'm not sure I understand this concern. Do we see this happening on
either side? Do we see IETF making "new" assignments outside of what has
been defined for many years (under the classfull system, IIRC)? Do we
see IANA trying to break into Class E space, for example, for new

I support immediate adoption of this proposal, preferably without this
last statement. I don't really wish to delay the adoption of this policy
by trying to force a formal statement out of the NRO nor delay
subsequent RIR allocations under this policy by compelling IANA to
coordinate these allocation efforts with IETF, when no such cooperation
is required.

(To complete this thought: if in the future, IANA chooses to break into
IETF space for allocations, we as a community could always write new
policy to reject the reserved space as invalid.)
