I object to section 1.3 Feature Detection. Removing that section, or
changing it so that it does not introduce new features or versions, would
satisfy my objection. The HTML spec discourages use of feature strings and
specs the minimal set of feature strings for HTML that are needed for
compatibility. DOM4 forbids new specs to add new feature strings or new
versions.

One of the ideas with event constructors was not only to introduce the
constructor, but also to get rid of init*Event() methods where possible.
So ideally, e.g. the WheelEvent interface would not have the legacy
method, since it's (I assume) not needed for compat with existing content.
