For these and similar reasons, I think it's best not to mess with this
too much. It should fail where it actually fails. We shouldn't be
duplicating that logic in a remote place to predict that something will
fail later. In some cases, this is rather safe and easy and useful as a
service to the user, but once it gets slightly complicated, it can only
go wrong.
