My experience is exactly the reverse.  I've never before seen a
removable-media device (floppy, Zip-drive, JAZ drive) that *did*
have a DOS "partition" table aka BSD "slice" table.  Surely you
would not expect a USB floppy to show up as /dev/da0s1?

AFAIK the reason for creating slices is to identify sections of
the device for use by different OS -- something often needed
for multi-boot from a hard drive but seldom on removable media.
I sure wasn't planning to use part of this SD card for my camera
to store pictures on, and the rest for FreeBSD backups :)
