However, that will make debugging very hard indeed. Not sure how big a consideration that is, but I know that I have often looked into the MW stylesheets to see how particular stylings are acheived when making my own css rules.

Just from a quick check of http://en.wikipedia.org/skins-1.5/monobook/main.css?55, removing all the possible white space will reduce it in size from 30882 bytes to 23411 bytes, saving 7471 bytes (24%). That's a drastic change in size, and if done would save a ton of bandwidth (over time). If you're concerned about readability, perhaps two files are warranted, a "readable" file and a "usable" file, and the readable one could be linked from a comment at the top of the usable one.
