This is also true of other filesystems however. I don't have experience with high IO on ZFS at those rumored 80%+ capacities however once a core filer fills up to 90% you start seeing the tickets rolling in and application performance tank. 80% if usually fine however. I wonder to what degree the performance degradation is on OpenZFS.

The problem is much more severe on ZFS and other CoW filesystems, hence the common warning. Filling an ext4 filesystem up to 80%+ and then removing files might increase fragmentation a bit but it'll not have that much effect on performance. On ZFS, filling the fileystem up once can kill performance permanently on that pool.
