I was on the other end anecdotally... so I was happy to see some
numbers. they code I put together to get this I'll pop up on github or
something, in case people want to see for themselves or futz with this

right, there's a balance between: "we tried to provide for a
reasonable situation for X years" and "welp, hit the xfer/black/etc
If marty's numbers for 1900 are valid (which they seem to be) and if
there are some large percent of that set that run new tlds for real, a
15 isn't going to cut it, and neither is a 14 (for long).

I don't think they really can... for a single entity (one corporation
that buys a brand-tld) and runs their own service, they can hide their
stuff in their existing space. For someone who runs this as a service
for others, they can't afford to move things in times of stress and
they can't afford tlda to be down because tldb upset the elbonians
this week :(
