When making a paradigm change to a core, infrastructure mechanism, it is best to 
assume the worst-case conditions, rather than best.

For example, I can assure you from first-hand knowledge that US$ 100K cost for a 
domain name a company deems desirable is not all that rare.  I would certainly 
not assume the global limit to be a few thousand.

More generally, the difference between allowing unbounded TLDs, versus limiting 
them by a price, involves very different strategic decision-making.  The former 
is massive and fundamental.  The latter is rather minor and likely to be viewed 
as tweaking.

So any analysis had better be made on the assumption that limits are from more 
natural and persistent characteristics, rather than from a current charging or 
operations constraints decision.

Not if, for example, the 99% also grew with the added legitimate traffice.

Again, the operations rule I've been taught is to base analyses based on the 
limit of worst-case scenarios that one can tolerate, not to make assumptions 
about reasonableness (other than there won't be any.)

ps. I assume (and hope) that the real DNS root experts will weigh in on this, 
here, soon...
