Theoretically, you're right. But how many "enterprise" intranet apps actually make use of cutting-edge HTML5 and JS5 features?

It's not about cutting edge or not cutting edge. The same inconsistencies are present in implementations for all the major specifications.

It's worse in most cases as there aren't fully built out tests, so it's even more difficult to converge implementations to the specifications.
