I'd definitely agree with the lack of usability-oriented features
being a part of why Plan 9 hasn't been commercially successful. In
general, it seems like Plan 9 focuses on being minimal above
everything else, whereas I'd say an ideal OS should focus on being
sufficiently general and extensible in addition to being minimal (in
other words, do things in the most minimal way that is sufficiently
general and extensible).

I'd say features like history, completion, and line editing really
don't belong in a shell. They should be handled by a separate listener
process with a simple API that shells and other client processes can
use for controlling them. That's one good example of Plan 9
prioritizing minimalism above everything else.
