What are you talking about? I mean _I've_ thought about how things
work, and considered the important cases when the current mechanism is
confusing in this way, and decided that this is a good solution.

Of course it works. The reason why it's a bit wierd is because the
input field is at the of the buffer, and _everything_ involving
text properties works a bit oddly at the end of the buffer. [your
proposed `solution' would have exactly the same problem!]

Yes, but people apparently don't like it (I don't really care). They
want C-e to go to the `end of something', not `the beginning'. Even
though the `background' is a field too by definition, people think of
the input field as being distinguished from the background, and I
suppose emacs ought to respect that.

I'm proposing changing the way the field-restriction functions work
(which are called by anyone that cares about a field) to not act like
it's a field when the field property is nil.

I suspect trying to do it through command remapping would actually be a
lot messier -- because you're only changing things at a surface level,
you have a lot more special cases to worry about.
[and in any case, the current mechanism (1) exists, and (2) works quite well]
I'd rather be consing.
