I'm not sure I see a default of 0 as being better than 8. 
If we're going to introduce a TP, and if everyone is going to set the TP all the time, then the default doesn't matter. If not, then I think we want to maintain 8 (or some similar value) for the same reasons that we had it before there was a TP.
