Well, I would like to know the issues as well, as I've already said I
think they should be described in the commit message.

But also, at the RFC stage the onus is on other people, particularly
people that want to keep the feature, to explain where it is being
used and why..

We need to decide if we drop the RFC and fix the implementation, apply
the the RFC, or add a deprecation printk warning, or something..

Please try to be productive here and concentrate on adding information
and not nit-picking the process! We all know removing a uapi is a big
deal.
