It's what happens with any teacher you get. Everyone has a way that they do things and their own opinions, and my opinion is use html5, always. Just so happens that this is also the opinion of the majority of web devs.

To be fair, you are right though - I should at very least educate people about this before teaching it. I will make sure to let my students know that if they would like to decrease the quality of their products based on 2% of people (that's data from 2007 as well, likely has gone significantly down) who browse with javascript off, then they should not use any html5 tags. Fair enough?
