What options or features does one get by putting the LUKS container in a

I am not aware of any technical advantages or disadvantages of LUKS on a
raw drive vs. LUKS on a partition. For me, it's more a matter of
personal habit/ psychology in the face of several computers, many
drives, and changing conditions over the years.
Prior to running encrypted drives, I used to wipe (zero) drives when I
took them out of service. Since migrating to LUKS partitions, sometimes
I wipe, sometimes I shred, and sometimes I just put the drive aside. So
now when I grab a spare drive off the shelf, I look for a partition table:
1. If the first megabyte has been zeroed:

David,
Thanks for the outstanding answer.
After thinking about it, and remembering that partitioning also detects
and marks bad blocks, I was then wondering if this was done also by the
writing of LUKS container alone. Anyone know?
