Letting the number of workspaces dynamically expand and contract would probably lead me to frustration. Currently I have 2 desktops that are static (web browsing and music) and 2 that are dynamic (for any two projects I'm working on at the moment). Whenever I want to look something up or change my music I know which space they're in, kind of like muscle memory. To use the desktop metaphor, I have a spacial picture of where things should go (i.e. soda is always in the same place.) Adding additional workspaces is just enough work that it isn't easy enough to accidentally do, and not hard enough to be adverse to doing. Frankly, I'm never working on more than two things at one time though. However, what would probably be the best would be the ability to save workspaces and then load them up again, much like OmniWeb and Opera allow you to do with browsing sessions.
On an evolutionary timescale the opposite seems to be happening though. I can't remember exact numbers , but the difference in size based on gender have been decreasing since about the time of Australopithecus (I think from males being 50% larger to around 10 or 20% larger than females, I read the article a while back). While the size differential can be very noticeable in some culture groups, the genetic change for humans as a whole is probably less concrete. For example, dogs have a wide variation in body size, but if you interbreed them then after a few generations you'll get a mongrel with a fairly average body size and shape.
I agree with you, having used macs while growing up (System 7) so bear with me when I say that
OS 9 totally let you tab windows (look in the bottom right)
(Not quite the same thing I know, but that cosmetic similarity would be enough for some people to claim ownership.)
