Come to think of it, a nice addition to the HTML-standards would be to allow adding an “optional” tag to <script> elements, indicating that a script is optional and can be ignored without breaking the site.
Don’t you think that would cause lots of sites setting their tracking scripts as non-optional?
Of course, but that wouldn’t be any different from today (every <script> is non-optional today). I get your point though and there probably have to be other approaches to this issue.
IMHO every <script> element should be optional. Of course that can’t work with everything (web apps need JS to even blink) but any forum/blog/wiki/whatever should be able to live without some fancy script hiding some reloads.
What are the privacy implications of not using frame options header?
It avoids clickjacking, also it has apparently been obsoleted, but I guess it’s nice to keep it around for older browsers.
