That would honestly be quite reasonable - but unfortunately, is a bit of a pipe dream. We certainly want to make it easier to make articles that work nicely between phones and larger devices (though, to be clear, today's changes are about tablets and above), but asking users to create essentially two different versions of each artice isn't reasonable.

The changes today are not the ultimate solution to that issue - it is a part of a puzzle that will be challenging everyone (us, editors, and many other websites) for a long time to come. We have a variety of interesting ideas around this, which we'll have more news on in the future (and should be less controversial than today's update).
