Thanks for taking the time to send this in! Will be taking a look shortly.

I assume it would be highly annoying to write a test case for this?

Looks like there are a bunch more changes that need to happen for ember-cli-pagination to work without array prototype extensions. It looks pretty doable tho. If you wanted to take a crack at it, I'd happily take a look when you're done and merge it in, but don't feel any obligation. Let me know, and thanks again for the initial submission!

By "work" in the previous comment, I mean for all the tests to pass.

FYI this is what I put into environment.js to disable only array extensions

'use strict';

module.exports = function(/* environment, appConfig */) {
  return { 
    EmberENV: {
      EXTEND_PROTOTYPES: {
        String: true,
        Array: false,
        Function: true
      }
    } 
  };
};
