Publishing and maintaining multiple versions because other hosting services aren't compatible won't be manageable for us. Microsoft's recommends using isolated hosting, because these kinds of issue happen all the time....

I see, is there an issue you can point me to for the problems with Twilio and isolated hosting? I'd like to help if I can.

Agreed, it would be great to be able to define the col-groups for other breakpoints.
