The default behavior of WGL, EGL and GLX is to choose a config that has /at least/ the specified number of bits, whereas the GLFW 2 behavior was to choose the closest match with very few hard constraints. Moving the responsibility of finding the supported minimum values to the client was problematic, as there's no way to enumerate supported configurations, forcing the client to perform multiple (and slow) window/context creation attempts. Not even the currently set defaults (24-bit color and depth, 8-bit stencil) is universally supported, as bug reports show.
