Yes, it will 'hurt' more to use SMR drives with raidz1/raidz2/raidz3.

... but I believe ZFS DRAID mode will not hurt that much on SMR drives.

In ZFS DRAID there is no dedicated SPARE drives - but 'spare blocks' are spread across the disks along with 'data blocks' and 'parity blocks' - this means that all drives 'read' for the resilver and all drives 'write' for the resilver.

... also the Sequential Resilver helps even more:
