So the message I've gotten from others is "Windows solves this problem
and Linux does not" and they were aware of the ability to set up a local
passwd file when complaining.

I think the question we have to answer is why is there a perceived
deficiency vs. Windows, and can we address that without fundamental
security problems. Appears the perceived deficiency would include 1) we
aren't working out of the box, only if you fool around with it and
possibly requiring the end user to run authconfig 2) the local/remote
passwords can get out of sync.
