I think such a thing could still be useful. It'll help figure out what kind of info apps are getting from a given system, and help determine if problems are app-specific or more general system/wine-related. It can also serve as a basic interactive test bed for various DX functionality that even users can run and look at, instead of being delegated to the wine test suite only. Plus it can check DirectPlay and DirectSound (a couple other components prone to errors), instead of just Direct3D/DirectDraw.
Wine needs a dxdiag.exe as some apps expect it to be present, like for example GameShadow. I once gave it a shot already, see http://bugs.winehq.org/show_bug.cgi?id=14118. A builtin dxdiag.exe would aslo be nice addition to wine imo.
