That, actually, is the norm. It is NOT normal to partition a raid array.
It's also not usual (which the OP has done) to create a raid array on
top of raw devices rather than partitions - although this is down to the
fact that various *other* utilities seem to assume that an unpartitioned
device is free space that can be trampled on. Every now and then people
seem to lose their arrays because an MBR or GPT has mysteriously
appeared on the disk.

Your approach seems to be at odds with *normal* practice, although there
is nothing wrong with it. At the end of the day, as far as linux is
concerned, one block device is much the same as any other.
