Try to implement the rendering engine of a web-browser. The standards keep growing. A much simpler model could have been drafted for web content. Instead we keep hacking onto HTML adding things like CSS, JS. Then we keep adding on to those add-ons. Clearly, people are building things that are not documents. So why do we keep adding hacks to this document model?

Further, when you you Google, Mozzila, ect... saying you can't you use a feature without HTTPs the effectively make HTTPs part the standard even though it's not written in the standard.

For instance let say I wanted to run HTTP 2.0 web server. The HTTP 2.0 standard does not require encryption. However, because none of the browsers vendors support HTTP 2.0 without TLS. I must setup TLS to make my server accessible. It's not part of the standard, but the big browser providers effectively make it part of the standard. I don't have a problem with crypto. I just hate the browsers forcing it to be basically part of the standards. When it should be optional.
