I'm unpersuaded by the arguments later in the thread that we should keep 
this port for its pedagogical value as a BITS_PER_UNIT != 8 port.  I 
think the criteria should be the same as any other port.

However, I do think that it's late to be making this decision, and I 
can't see any harm in delaying obsoletion until 4.0.1.  That will give 
potential maintainers a fair chance to step forward.
