The idea behind faster idles and delayed shifting is to light off the cat and oxygen sensors earlier, I guess it reduces cold emissions. Most of the cryptic things modern engines do make more sense when you take it as a rule of thumb that ECU strategies favor lowering emissions.

I don't know that I'd go too far in loading a cold engine, but definitely better to start and drive than idle. I don't have a choice when leaving the house, I have a nice little uphill at the end of the block. I say just get in and drive, settle into your hypermiling as you go.
