RE: [sv-bc] Case Statement Enhancement Proposal Idea

I believe I understand the synthesis viewpoint here.

There really isn't a simulation-synthesis mismatch.  The warnings in
the simulation output mean "Your logic is incorrect.  It violates
your assumptions and will not work the way you expect."  Lo and behold,
the synthesis output doesn't work the way you expected.  That is not a
mismatch.  You just chose to ignore some of your simulator output.

If users are going to ignore the simulator warnings when the unique
qualifier is incorrect, and don't want synthesis tools to assume that
the qualifier is correct, then there is no point to having it in
the language in the first place.
