Comment (by joehoyle):

 > I think it should be opt-in - as we discussed earlier, there are
 important routes that do not support pre-validation at the moment and
 sending batch requests with validation=pre will not work as expected. With
 opt-in approach, the batch processing endpoint could be merged first and
 then more and more routes would opt-in to batch processing as time passes.

 I'm not sure I agree with this rationale. Making this opt-in will make
 this feature be of quite limited value. I think in many cases people won't
 use Batch, so won't ever even add it to their route registration.

 If a route doesn't support pre-validation (which I think is to say that
 validation is done directly in the `get_items` (etc) handler, why would it
 matter? Route callbacks can always create errors, so avoiding that I'm
 assuming is not the issue.
