DAYOFWEEK command

Exactly. This is what I meant by "needs another function to read the setting". Without it, configurability would cause unsolveable sideeffects in programs.

Like you, I think it is good as it is, except for that most day-of-week functions I have seen implemented in libraries or shells elsewhere return 1 = Sunday rather than 1 = Monday (or even 0 = Sunday), so the results may be unexpected to some. I have also seen two sets of functions being implemented to avoid this, like in DOW (for 1 = Sunday) and ISODOW (for 1 = Monday) etc., perhaps still an option for the Prime as well...

Yes, it would be nice to have, so that the calculator could give acoustic feedback on errors or touch screen gestures (only if mutable, of course) and be used as an alarm timer as well. Also, kids might have fun to implement some rudimentary music programs, like probably many of us did when we were young. IMO, by not providing an option to output sound (it doesn't need to be sophisticated), HP is missing a sales incentive. A beeper is a checklist item for some.
