Drew,
I actually talked with Press Maxwell once, a career highlight. Most of what he saidI also did a master plan for one of his later courses, and talking with members, they said he was pretty blasé about design at the time, telling his shapers, "Give a 2 mounder here, a 4 mounder there, and a 3 mounder over yonder, etc.
I recently played a Press Maxwell, Pinecrest in Longview, TX, which was said to be nearly untouched since he expanded it to 18 holes in 1958. Looking at historicaerials.com, I find that it was changed some time between 1957 and 1970, although I don't know if Maxwell did the only changes. (DA Weibring added a range and changed the range sometime post 2000)
Looking at the historic aerials, it is hard to see big differences in the green sizes. Looking at it in person, all I can say is the greens have grown way in, not connected to the fw anymore.
As to the philosophy itself, small greens on long holes and vice versa seems to go against tradition, except a few of us use at least one small green on long 3 or 4 par holes as a way to test long iron accuracy, given distance increases these days. Building big, subdivided greens on short holes is fairly common, since small ones would get eaten up by ball marks.
I agree most courses decide they are big green or small green courses, or can only afford X amount of green. To supers, any bigger than the minimum they like for maintenance is a waste of resources, any smaller frowned up as not giving enough cup space. Even golfers are funny, noticing when a green doesn't look like the others, because it's different in size. My response? Well, that was sort of the point, no?"
I even had a shaper build the green to the average size. He noticed I had designed a much larger green on one hole, and figured I made a mistake and would want to make it the same as others.
As to the strategy, yes they should vary. Good players will notice if one long par 4 has a big green, another a small one, and others with average size greens with distinct features, for example. Nothing wrong with having one green harder to hit than the others, and maybe one much easier, with (as you mention) perils for being too far from the pin.
