What, the extension that restores the original functionality doesn't count as a "way to restore the stripped functionality"? And saying "adding features I don't like counts as making your product less functional" is kind of cheating.
While true, the vast majority of programs people need Wine to run are closed-source. An architecture-agnostic version of Winelib which could be included with from-source programs on non-x86 systems might be viable...but frankly, people are more likely to port their program to Linux than to Sparc.
Getting Wine to run on a processor architecture not native to Windows would require emulating an x86 processor. Say it with me: Wine Is Not an Emulator.
