Dear John - I think users can cope with six plots offered by one function, with four of them given by default, and the two remaining plots alternative ways of presenting the information in the final default plot. The idea of plot.lm() was to provide a set of plots that would serve most basic purposes.
I rather like added-variable plots for examining influence and leverage on
coefficients.
I think that plots of this type are compulsory. termplot() is a pretty good start.
