Your point is valid that giving your html tags id's are like defining global objects.
In fact some browsers give you warnings if you have two tags with the same id defined.
However this is by no means a new 'feature'. Maybe it's time to take a brush up on the DOM model.
Oh. And yes. The web technologies are a whole pile of worms in itself. Just think of the hacks that Javascript frameworks go through in order to render things just somewhat fast.
