Note that not all terminals are equal, my terminal has some issues with
boldness:

Also, there are and always will be personal preferences.
Should dmd really use boldness for the keywords? Why not white? Or pink? etc.

This is highly subjective and I don't see any reason why it shouldn't be
allowed.
