Was it simply due to the idea of making variable sized discs? IE if you
look at, for example early copies of James Last Tango, or Roxy Music Avalon
you see that there is a huge part of the surface not used and it can be
used as a mirror. Perhaps back in the day, it was thought that one could
crop off the disc so not only could we have singles sized ones but old
vinyl album length ones as well.

Nowadays of course the whole surface looks used even when its not. Makes you
wonder if there is some secret info in those outer areas....

By playing from the inside out, you can use multiple sizes of media -
that's pretty much it.
