Don't you think that with clipless you are able to engage more of your muscles? But, I do appreciate being able to ride using any old shoe now (at least on that old bike!).

I think we're always good.
Somewhere there was actually a study that may have proved you wrong, that upstroke pull doesn't really gain anything - this topic comes up all the time on google groups - maybe I can search it out - weathered in today.
Platforms are certainly a tradeoff - you can find a point in too fast spin where they just don't stick. I still like my toe clips and touring shoes and feel more confident in them riding aggressively than charging on the platforms.
But I have stood on my platforms on some aggressive leaning climbs with my feet almost vertical, and they stick amazingly.
There are many reasons why modern thin platform pedals are better than any offerings in the past.
The people who pick them to race are racing downhill.
