Yes this became obvious as questions were asked.  E.g., one question pointed
out the problem with big jump in root scaling report graph.  It seems to
assume all TLDs are signed and publishing DS records at same time (that's
the big jump), it's far more likely it will be a gradual take up of DNSSEC
by TLDs (and some may never deploy it), therefore the growth in size and
rate of change will be slower, not immediate as the graph suggested.  The
other point raised was what exactly are the assumptions that determined the
root server capacity curve (the blue line), change the assumptions and the
capacity curve could start from a much higher point on the x axis.

IMO, it would be very imprudent to draw any recommendations from the
existing report.


Another thing and the model from TNO includes something of it, the issue of

Yes,  I agree.


As I said before, big mistake from ICANN is that we should have done all

This raises another critique of the argument to sequence DNSSEC first, then
addt'l TLDs, IPv6, etc.  If we're only doing a 100 TLDs/year then the "big
jump" becomes a non-factor for a while - so we shouldn't rush signing the
root.
