Not an application, but the sysadmin do cares about it. And most
rootkit detectors don't have any other way of checking if a
tcpdump-like tool is running.

which is confusing for users. But I see a benefit in exporting
promiscuity as a read-only value, and I think it's pretty trivial to
provide it.
