I don't understand.  How does emacs know when it's currently in an important
case...

I said 'indicates' -- as the major example of using this feature doesn't
work, and need to be reworked using more machinery (rather than less).

Ok, but it sometimes does make sense to navigate inside the prompt.
C-e -> goto end of prompt (= start of input), another C-e -> go to
end of input.  Isn't that how it's working now?

I thought you were proposing to change, end-of-line and other
commands to behave differently if point is "inside" a field.  I
referred to that as "messy" (compared to doing it through
command remapping).
