Negative priority is potentially a hint to the UA not to display to the receiving user, but that requires the client to do the right thing and treat negative priority as offline/unavailable.  Few clients (most likely none) do the right thing today.

I believe it matters if that information is concerning or not.  If not, then simple negative priority is probably fine.  If it is, then negative priority + invisibility is necessary.
