What happened to the zbp instruction set?

Back in 2021 or so, the bitmanip extension draft included a number of really powerful and general operations (grev, gorl etc) that if I understand correctly got moved to a "zbp" extension when bitmanip got split up. From then, as far as I can tell, nothing happened with ratifying zbp.

Is this more or less correct? Is there a plan to ratify it eventually or is it just outdated?
