Oh absolutely. I don't dispute that. Given infinite time as you said.

But I gained a 5x reduction already. I would prefer moving to some other 
part of the kernel where another 5x reduction could be achieved now 
rather than postponing that after I'm done rewriting the interface for 
all UART drivers.  Maybe someone else will feel inspired and take on 
this UART driver modernizing task (that could be a nice mentorred 
project for example).

PS: FUZIX is a real piece of art  ;-)
