Ubuntu enables discard by default in all the installers, all filesystems, and all layers (e.g. mdadm/lvm/luks discard).
Assumption until now, has been that it is harmless, when underlying storage doesn't support discard and always non-harmful when it is supported.
I agree, we should revert discard support for ESE volumes in Ubuntu for now.
