No.

We didn't adopt the biosdevname names in udev since they didn't actually
deliver what they claimed to deliver, and resorted to naming things
after probing order in the end.

Use biosdevname if you want biosdevname names, it still works.

Sorry, but this has no place in systemd/udev. We didn't adopt the
names for a reason.

"unusable"? Can you elaborate what you mean by that?
