Is there any merit to allowing users to set flag indicating tagName/className for view is inside template?

I've see this question come up more than a few times. I have mixed feelings on it.

Users want to do something like:

var MyView = Marionette.ItemView.extend({
    templateOnly: true,
    template: _.template('<span class="myView"></span>')
});

which would be equiv. to:

var MyView = Marionette.ItemView.extend({
    tagName: 'span',
    className: 'myView'
});

I can't imagine this would be exceedingly difficult to do, but might be a slight perf. hit for the extra check when rendering, but it would allow all HTML to stay inside the template.

Thoughts?

We're having this conversation over in #2357.
