I wonder how much of the 'thin-ness' was related to the frequency response differences between the cardioid and omni mics, and how much to the different character of the stereo arrays. Spaced omnis always have a beguiling low-end spatiousness which makes them sound a lot fuller than they really are....
But yes, I take the point, and agree with your preference for omnis... I just don't want people to think they can't make acceptable and pleasing recordings with other types of microphone. And of course there are many, many situations where omnis are just completely impractical anyway.
But solo recitals on a big grand piano in a decent sounding room? Absolutely: spaced omnis all the way! :D
