Suggestion: More realistic nukes.

Games are not about realism, they are all about fun and realism is present only if it does not ruin fun. So what in fun department such more realistic nuke will have?

Not all units destroyed, some stunned by EMP are left alive.

This would annoy me when i am nuking enemy, because there is always possibility that some fabber survived, so i need to recheck few minutes later if he did not start rebuilding at that location.

As for receiving nuke side, this also would not add to fun. I either forget those stunned units, and try to recover somewhere else, or i need wait for units to be active again. Doing something elsewhere then returning to nuked place to check if anything survived, this IMO adds to annoyance not to fun factor.

And targeting orbital layer (and killing all units ther) is good idea, would be great to clear out enemy orbital defenses. But that if antinukes do not protect orbital layer, this would make nukes somehow useful late game.
