Yes, that's exactly what it is.  There's no point calling it fsck
because fsck fixes individual filesystems, while ZFS fixups need to
happen at the volume level (at volume import time).

It's true that this should have been in ZFS from the word go.  But
it's there now, and that's what matters, IMO.

It's also true that this was never necessary with hardware that
doesn't lie, but it's good to have it anyways, and is critical for
personal systems such as laptops.
