Earlier versions of Mac OS X would install the development tools in /Developer on the hard drive too.

Right - it was more like Utilities than Documents. A folder for a type of app that not every user needed, not for documented created for a purpose.
If you look at the video [1] you can see it installing developer tools into the NeXTDeveloper and NeXTLibrary folders. So it's quite possible Apple just did a find/replace and removed the prefix.
