If you don't mind my asking, and even if it's just a guess:

1) do you feel squotas are likely safe and I hit another bug?
2) any chance it can be block-group-tree instead? Are those 
   considered reasonably safe? (I enabled due to the number of
   snapshots, 100+, and being told it's bad for perf to have that
   many, which block-group-tree is supposed to fix)
3) anyone still taking bugs for btrfs check --repair since it
   fixed nothing on an unmountable filesystem
4) anything useful to anyone in my broken filesystem which might
   be easy to fix but not by me before I give up, delete it all
   and do the multi week restore?

Thanks,
Marc
