Re: exactly how unsupported is com.apple.kpi.unsupported?

I'd like to use a symbol (m_get_packets) which I can find only in com.apple.kpi.unsupported.  However, the name makes me a little nervous, and I was wondering what was meant by "unsupported"

Granted the name sounds less than encouraging, but at least  com.apple.kpi.unsupported does not seem to bump its  OSBundleCompatibleVersion on each minor release.   This makes me think that its at least a little more stable the com.apple.kernel.

What's the policy for changes to things in com.apple.kpi.unsupported?

It roughly translates to "no lifeguard on duty".  We don't make any promises about the release-to-release compatibility of anything in the "unsupported" kext.  From a practical standpoint, we tend to leave things in there alone (I don't think it changed from 10.4.0 to 10.4.1).  When we do make changes there, it will usually be to remove symbols.

So:
1) Don't use anything in com.apple.kpi.unsupported.
2) If you do use it, don't expect it to work in the next release
3) If it does work in the next release, goto 2

Cheers,
