I don't think we should take this change or accept this feature in general. It 
seems that of those who have spoken up, the WebKit community is not in favor of 
this direction.

Even though the specific change in that patch is relatively small, supporting 
custom MIME types has significant disadvantages:

- Creates interoperability issues with other browsers.
- Fragments the web
- Opens us up to further requests to add support for similarly niche MIME types 
in the future

If CE-HTML and HbbTV content is fine to process as ordinary HTML, then it 
should be served with text/html MIME type. That would avoid all of these 
problems. If a consortium decided to create custom mime types instead, then 
they made a mistake and should fix it. In some cases, when the technology is 
compelling or there is a wealth of existing content, we live with arguable 
errors in the standard. But neither of those considerations applies here.
