There are additional IEEE 802.11 information elements, including
identification and length bytes. The data area can include one more
multiple IEs (e.g., WPA, RSN, WME). Capabilities, listen interval, and
current AP would be from other ioctls.

I'm not sure what you mean with this. Cipher configuration is an
optional mechanism that some drivers can use for WPA configuration. This
is especially to make it easier to use drivers that were originally
designed for NDIS since they generate WPA IE based on the cipher
configuration whereas some of the (non-NDIS) drivers that I have worked
with get WPA IE from the Supplicant (i.e., they can share the same code
for this) and can ignore these values.

What's wrong with using netdev for this? I think this was the result
from the last time the topic of adding a new list came up and I don't
think anything have changed since then. As long as people don't complain
about getting too much messages about wireless development on netdev, I
don't see much point in adding a new list.
