It seems obvious enough that parent is talking about changing the behavior of innerHTML within their own application, not for browser makers to change the implementation. It's unfair to take the most uncharitable interpretation and upbraid the other commenter for being insufficiently defensive[1] when they pressed "reply".

Doesn't seem obvious unless your dutch.
Especially as the first things I would think obvious is: if breaking the behaviour of innerHTML is not a concern for your software why keep it at all? Delete the property or make it readonly.
