In the long run I think that's the way to go.  But implementing that is 
more work than I feel like doing at the moment.  For now I've gone with 
an approach that was easier to program, more like the current setup.exe. 
 If the solver finds problems (including missing dependencies), the 
user has four choices on the Prerequisite page:

1. Click Back to go back to the Chooser page, with the Pending view 
showing the solver's default solutions.

2. Click Next to accept the default solutions.

3. Uncheck the "Accept default solutions" box and click Next.  If the 
user dismisses the resulting warning, setup will go ahead and do what 
the user requested.

4. Cancel.

Once the inevitable remaining bugs are fixed, I think we'll have a 
setup.exe that's better than the current one, with possibilities for 
further UI improvements along the lines you suggested.
