Without diving into this, just sharing my view on auxdisplay subsystem:
I consider it _mostly_ (like lim->100% mathematically speaking) as for
7-segment and alike displays, not any comples RGB or so devices. If
those devices are capable of representing characters/digits in similar
way, we may export linedisp library for them to utilise.
