Thanks, this patch would be more consistent way of removing these.

In general, I try to avoid removing any control interface commands that
may be in identifiable or expected use unless there is a very strong
justification for doing that (e.g., some issues with the specific
command that cannot be fixed without doing incompatible changes).

This patch is removing the following commands:

I'm not aware of BSS_EXPIRE_* users. Those were added to the control
interface with matching changes in the D-Bus interface and my
interpretation there was that the D-Bus interface would have been used
for the specific use case.

I do know that AP_SCAN has been used. It was used in Android until 4.2,
i.e., it was removed in 4.3 in this commit:

As far as Android is concerned, I'm trying to maintain support for last
couple of AOSP releases which I'd say would be 4.4, 5.0, and 5.1 at the
moment. As such, it may be justifiable to remove AP_SCAN from Android
view point.

If anyone happens to be aware of any other uses of these three
wpa_supplicant control interface commands, please let me know. I'm not
applying this patch now, but I may apply it later if no real users for
the commands can be identified.
