I suspect this part of the request would:
I’m just thinking that this part of it probably involves physically closing a circuit, like a “dumb” doorbell button does, but I don’t actually know. 
Even without that part, though, I think that a basic virtual button press capable of initiating chimes other than built-in wired chimes would still have the potential for a lot of utility, including ringing other doorbells, and should absolutely be doable via firmware/app/backend updates. Making something like that available to the user as a selectable action would be pretty swell. I agree that taking advantage of any available Edge AI features should improve speed, too, though in the AI-enhanced scenario I outlined the delay might actually be a benefit because it potentially gives the delivery person additional time to actually press the button (and obviate the need for the automatic ring). For something like that, the timing (lockout delay or whatever) could also be user selectable.
It’s a wish, though, so I’m wishing for a full simulated button press that ding-dong!s my mechanical chime along with all the rest of it.
