Comment (by TimothyBlynJacobs):

 > I'm not sure I agree with this rationale. Making this opt-in will make
 this feature be of quite limited value.

 My rationale for the opt-in flag is more along these lines:

 > While theoretically any properly coded route wouldn't have an issue
 being used in this manner, not every route is properly coded

 The REST API is of course designed to be reentrant, but I've seen a
 surprising number of instances where due to how people have implemented
 controllers it wouldn't be. In particular for non-get requests and things
 with permission callbacks.

 If one of those routes are included in the batch, the results could be
 bizarre or completely broken. If we're fine with that, then I think we
 could switch it to an opt-out mechanism.

 > I think in many cases people won't use Batch, so won't ever even add it
 to their route registration.

 So this would be for when a developer wants to make batch requests for
 another plugin's routes?
