It sounds like folks think testnet is useful enough to continue maintaining=
.

I think it's a fair point that testnet should strive to be as similar to
mainnet as possible. If we fix the difficulty reset edge case then that
will arguably make testnet EVEN MORE like mainnet by removing the "block
storm" phenomenon.

Changing the supply schedule is an interesting proposal, though I'd counter
that fixing the difficulty reset will naturally make the supply schedule
more evenly distributed over time, plus we can hopefully move toward
resetting the network before long. I'd be slightly worried about changing
consensus rules on testnet that deviate significantly from mainnet because
I bet there are plenty of systems running that validate that rule or make
assumptions that it's the same as mainnet, and deploying such a change
could cause far more grief for the developer ecosystem.
