I agree, that on basically every system today there is no need for the
monochrome or VGA16 logo.
But I'm not sure about the historic/exotic platforms, e.g. m68, sparc
and so on.

So, maybe instead of dropping the default "y", we should e.g. do:
+	default y if SUPERH
+	default y if XYZ (some other architecture/platform) ???
+	default n  (for all others)

The question is: Which arches may have needed the VGA16 or monochrome logo?
