But dont you think some of the creative decisions could have been based around the limitations of the technology at the time and that re-tinkering them later on would change the presentation as originaly intended?
Almost certainly true. So much would be done differently if the Beatles were recording today. But they aren't.
I am keeping in mind that I am on a high end audio based forum and the very word "Mono" has some people breaking out into a cold sweat.
I don't know; my G68 has a mono DSP preset.

Having said that, I like the soundstage broadening that Trifield achieves with a mono mix.
