Yes!

It's a common problem in my opinion on the LKML that many kernel developers assume
that users of certain drivers and kernel subsystems are present and active on the
kernel mailing lists to be able to raise their voices in these discussions.

If you want to find out whether some parts of the kernel are actively being used,
it's better to ask on distribution mailing lists because it's way more likely
to find any users there.

I try to be present on as many kernel mailing lists as I can to be able to answer
these questions, but sometimes there is just too much traffic for me to handle.
