display_exceptions in the config - do we need it?

[weierophinney]

In my development I stoped getting exception errors. I checked the Application and verified that:

'display_exceptions' => true,

Later I discovered that zf-rest override my setting at:
https://github.com/zfcampus/zf-rest/blob/master/config/module.config.php#L53

My solution was easy, I moved Application (and my module) to the end of the stack and behaviour returned to the expected one.
My question is. Do we really need it in the zf-rest configuration?
