Wasn't your use case that you wanted to specify form fields in
a given order (LIST), render a default view of the form in that
order (LIST), and, later on, access the field specifiers in an
arbitrary order, based on their key (DICT). Sure looks like it's
the LIST aspect that's important here...

You want an ordered dict because you say you want one, not be-
cause it's the best way to address your use case. That's fine, but
it's not really related to the question asked in the subject line.

Copying the entire data structure hardly qualifies as "creating a
new view". dict() doesn't do that; in this use case, it doesn't cost
you anything to use it.
Everything has a cost in Python. Things aren't free just because
they're implemented by some other module.
But when things are free, they're often a good choice.
