The name of the mailing list is not "mdadm", but "linux-raid".
http://vger.kernel.org/vger-lists.html#linux-raid
"Welcome to the linux-raid mailing list, hosted on vger.kernel.org.
Discussions on this list should be relevant to using RAID technologies
with Linux."
Hardware RAID isn't discussed here often, but it is on-topic on this
list. LVM, dm-crypt, dm-raid, Intel Matrix RAID (hardware/fakeRAID)
management integration in mdadm, bcache, etc, are also discussed here,
just not often. Likewise, they are on-topic.

No.

Yes, something else. You've been under the mistaken impression that
this mailing list is dedicated solely to the Linux software RAID driver
and management util, aka md/mdadm, and that hardware RAID is OT or
taboo. This is simply not the case.
