This seems pretty useful to me.  I think we might want multiple sets of
keys:

0. No reorgs

1. Periodic reorgs of small to moderate depth for ongoing testing
without excessive disruption (e.g. the every 8 hours proposal).  I think
this probably ought to be the default-default `-signet` in Bitcoin Core
and other nodes.

2. Either frequent reorgs (e.g. every block) or a webapp that generates
reorgs on demand to further reduce testing delays.

If we can only have two, I'd suggest dropping 0.  I think it's already
the case that too few people test their software with reorgs.
