The script posted at:

to mark the addresses as deprecated.

That requires you to know the SLAAC address (and thus the MAC address) in advance, so not always applicable. It's also no longer "stateless auto configuration" if you have to hardcode the address in your startup config.

I said there was an existing workaround, I did not say it was perfect.

And in that context it's reasonable for me to require real guidance from the IETF before we make a change.
