I think I know why it does this: for disks without NetBSD disklabel,
you can but an incore disklabel (disklabel, mbrlabel, ...) but then you
had to keep a partition open, otherwise the in-core label would be lost.
I think now it re-reads the label only when the device has changed.
I think this went in as a side effect of the changes I made to open a device
without media, but it was intentionally left in.

Doesn't 'disklabel -r' re-read it ?
