I was only an entry level engineer back then, but I was also told that the mandate was to fit an entire symphony on one disk; Beethoven's Ninth being the longest running length.

Way back in the early 80's, that was the story that was being told and there was a lot of screaming about how the 44.1khz rate was a big compromise.IIRC the origin of 44.1KHz had to do with the fact that digital masters were sent to the pressing plants on Sony 1630 U-Matic videotape, and 44.1KHz is a workable sampling rate for both PAL- and NTSC-format units to put three audio samples in each line of video.
But most of the early pro digital recorders and devices used sampling rates from 32KHz to 50KHz, in depths from 12 to 16 bits. In this, there's some great-sounding gear (a particular Weiss delay comes to mind), some horrible-sounding gear (I'm thinking of an early Lexicon delay), and some stuff that can go either way depending on how it's used (like the 3M Digital Mastering System). There was (and remains) no simple, constant correlation between the exact sampling rate or bit depth and the sound quality of the unit.
Personally, I think the Red Book standard hits a beautiful compromise on a whole slew of engineering criteria, especially when you consider all the challenges for the media and hardware manufacturing that had to be met for it to become adopted on a worldwide mass-market scale. It's easy to look with hindsight and think they should have done this or that differently, but one can do that just as easily (and brutally) with the LP format. The engineers of the time of course realized that it had its limitations, but they designed a music format that is remarkably durable, reliable, convenient, consistent, and economical . . . and if care is taken in the production and playback processes, it can sound really good too.
Suppose that instead the CD was i.e. 8 inches in diameter, and based around 88.2KHz/20bit PCM, extremely robust parity-based error correction with buffering, an S/PDIF interconnection standard with a separate word clock, etc. etc. etc. The question is, would this format be so good as to have completely avoided the whole "digital-vs.-analog" polarization?
I think the obvious answer is that it wouldn't . . . and as audiophilia is so rampant with binary (sic) debates, this was going to happen no matter what. The same personalities would get into the same arguments, and today be talking about how nothing stripped the "soul" from the music like that sinister conspiracy that brought us 88.1KHz/20-bit audio.
