Where to put Ember Framework configuration?

I’d like to be able to override the default event for the action handler (reason below), but this is currently hardcoded to ‘click’ in the Ember source, https://github.com/emberjs/ember.js/blob/master/packages/ember-routing/lib/helpers/action.js#L301

I’ll submit a PR to change that hardcoded “click” to a property that can be configured, however, where should configuration like this go? One option is using the Ember ENV, eg.

var action = {
  eventName: hash.on || Ember.ENV.ACTION_HELPER_EVENT_NAME
};

Is using the Ember ENV for configuration like this the way to go? Or is there a better place to put this?

Reason for wanting the change.

When running on a touch device, I want the actions and links to be triggered on ‘touchEnd’. When running on a non touch device, I want the actions and links to be triggered on click.

I can get this behaviour with links by reopening the link view:

Ember.LinkView.reopen({
  eventName: ('ontouchstart' in document.documentElement) ? 'touchEnd' : 'click'
})

However, because the default eventName of the action helper is hardcoded in the source, I would need to override the helper or change all my actions in the code to do the lookup themselves:

<div {{action someAction on=App.actionHelperEventName}}>

Ideally, I’d be able to configure the default event name for the action helper.
