Yes, of course, that's better, when it is possible, but to work usefully
(as opposed to simply substituting a dkN  device name with a wedge name
like sd0a) there needs to be somewhere in the partition format to store
the labels.   The proposed scheme seems like it would at least make it
easier to have one fstab file which would work whicever device number
is booted.

I don't see the lack of the ability to specify the partition in the same was
as nearly as big an issue - the device knows which of its partitions is
the root, and that root has an fstab file which indicates itself as the root
(if there's another root partition there, that one has its own fstab file).
So, that's not really a problem that needs much in the way of solving,
not in the way that filling in thye device number needs.

I have no idea what resizing wedged has to do with any of this.

Oh, yes, of course - though that makes no difference, blocks used are
blocks used, whatever file they're in...
