My current screen is a 13.3" 1440x900 LCD, resulting in about 127DPI. I was like "WTF has happend???" when I upgraded to 1.7 and saw everything in 96DPI.
Why ignore a valid information we already have? When someone wants to override this, he perfectly can do so. I don't see the point why everyone who wants to have the correct behavior has to configure it by telling xorg "you have the information, use it", it should be "the information you have is wrong, please use X instead" as the old behavior was...
Oh, and btw, which "other desktop environments"? DPI is dots per inch, there can't be any other interpretation than "how many pixels/dots are used for one inch on screen".
