Really?
Well, that makes sense.

One could argue that the ISO 9660 filesystem implies a partitioning,
perhaps. (^& So, /dev/cd0e as the sole partition would make sense
to me.
Speaking for myself, I would expect to use the same disklabel
partition letter for both these cases (and for floppies). Knowing
that that expectation is wrong, I can deal with it, though.
Thanks.
