And considering image size, throughput within the machine, memory access time, power requirements, you know--rather than merely intuit--that the current
hardware platform has these capabilities?

The problem is people only care about the features they want, and not
anything else. I feel if an added feature won't in any way detract from
what the device is meant to do, then it should be added. It would be
extremely easy to add the batch mode in the time all these messages have
been being posted a programmer probably could have it done already.
Making it read light text on dark backgrounds, something also important,
will take actual testing and possibly some research and much more
programming. Try to think in the big picture. I actually never use the
view finder, I basically get perfect orientation every time without any
help, but I fully understand why some people may need it and may use it
all the time, so I wouldn't say it shouldn't have been added.
