Comment:
As noted on the mailing list, this is already possible by setting
`TEMPLATES ['OPTIONS']['string_if_invalid']` to a class with a `__str__()`
that raises an exception. A proposal from the mailing list thread is to
add a new `'if_invalid'` option that's a callable which would allow more
advanced behavior (raise an exception, logging, etc.). Tentatively
accepting that approach. See #24199 for some related information about the
problem.
