The addition of hasUnwantedCapability was late in the release
cycle and does not simplify the API enough to be worth it. The
recommendation is, in a future release, to do something more
complete: not just add something like addUnwantedCapability, but
also deprecate all the NET_CAPABILITY_NOT_xxx constants and add
opposite NET_CAPABILITY_xxx constants for use with it.
