Comment (by Simon Charette):
So we've got two approach we could take here.
Determine that it was never meant to work and document it or use a
clemency based approach where we deprecate this behaviour by ignoring the
`output_field` of `Value` source expressions in
`Expression._resolve_output_field` when it fails with `FieldError`.
I'm surprised `Coalesce(F('field_decimal'), Decimal('0')))` doesn't
actually work.
