No. You merely "recommended" that it be the #1 item in the TODO list, which forced me to fix it fairly quickly for r8712u.

Most of them were in the kernel before mac80211, and have been given a pass as part of a "grandfather" clause.
Unfortunately, I forgot the main reason for development in an off-line repo. I do not have one of these devices, and I have drawn the line at purchasing a $1000 Lenovo tablet just to get one. Making "small" untested changes in the off-line repo for the users to verify is a lot simpler than working through staging, no matter how accommodating you are. :)
If someone wants to donate a device, that would speed up the process.
