I think that is well known amongst storage experts, though maybe not everyone who might be interested in using ZFS for storage in a professional or personal application. What I’m curious about is how ZFS’s full-disk performance (what is the best term for this?) compares to btrfs, WAFL, and so on. Is ZFS abnormally sensitive to this condition, or is it a normal property?

In any case it doesn’t stick out to me as a problem that needs to be fixed. You can’t fill a propane tank to 100% either.
