The underlying serial field supports digits and more (in fact it's
really an arbitrary 20 byte buffer).  However I excluded digits in
this case because the usual Linux naming scheme for partitions is


where <name> ends in an alphabetic character (eg. /dev/sda) , else:


where <name> ends in a digit (eg. /dev/mmcblk0p1).

If we allow people to use a label that ends in a digit then we'd
(probably) need to abide by this convention too, which makes things
complicated.  I agree this is not ideal, but also we can relax this
restriction later.
