In the hypothetical case that we would look at the current operation
of the root create a standard based on that.

It's been a while, and I don't recall the exact numbers, but some time ago
I looked at an estimate of how often a copy of the root would be needed if
all recursors switch to local root. I used root priming queries for that.

If you take that number and multiply it by the 1.4 MB that an AXFR of the
root currently takes then you'll get a pretty big number.

That doesn't say we must do or do not do something. Just that in my opinion
we shouldn't give too much weight to how the root is currently signed.

If we think that CDNs for the root are essentially for free, then let's just
write that down.
