The danger here is that you push too much, but the actual response will still be delivered almost as fast (due to non-blocking behavior in HTTP/2 connections), so sure, it's not optimal, but there are a lot of use cases besides static assets where it is very useful.
So you’re pushing unrequested data to everyone regardless.
h2o tries to solve this problem with a special cookie. More here:

But without something like that it’s a feature that will never really gain traction.
