It would exclude things like speech recognition and other accessibility software though that simulate user actions for good reasons.

Not necessarily - software that simulates input could in itself be protected with DRM, and interact with windows TPM systems.

As for the nay-sayers - well, the nay-sayers say nay to Microsoft in whatever they do, so it's not really a concern to me!  Ultimately allot of UAC popups occur because the OS can't tel the difference between a 'simulated' input or action, or a user command that it is genuinely coming from the user by mouse click, or keystroke.  A way needs to be found to fix it.
