I know about limitations in Kernel and have seen some efforts in the past
to avoid this. but generally I don't think it would be successful to go down
the road to allow slashes.

It would take some time to geht used for this names, anyway...
In your link below I have seen "ID_NET_NAME_ONBOARD_LABEL=Ethernet Port 1"

can anybody explain where this label is being exposed to userland tools for
display and management purposes?

Many thanks, Holger
