I don't think it's used by default for IMSM raid installation. That's why your devices were likely set up by dmraid first. When you mentioned in a previous comment about installing dracut-core, this automatically installs dmraid with kpartx. Mdadm never gets involved. When I've manually installed mdadm for IMSM raid, I first remove dmraid. That's the only way I was able to install Ubuntu 16.04 on top of IMSM raid1 via mdadm reliably.
