Hear, hear!
I'll at least be restarting the server temporarily with a blank world on 1.11 for this upcoming weekend's adventure times.
As for our more permanent world, I'll be happy to dig out my old trimming scripts again. I'm sure there's been a
little bit of expansion since the last trim, but it doesn't look like much or any. That should make picking the right chunk files an easy job, at least.
I think a new seed for the trimmed areas could be fun! We will face the Cliffs of Jeb, of course, but that's nothing a few stacks of TNT in everyone's inventory wouldn't fix.
