mutation events, why not making them cancelable?

Hello,

The mutations events look interesting with regard to content or ad blocking,
but unfortunaetly are not cancelable.

Why not make all events cancelable or add events like
"beforeDOMNodeInserted" or "beforeDOMAttrModified"?

events that are fired before the change is actually made and give a
reference to the affected node and info about the intended modifications, as
well as making this type of events cancelable.

What do you think?

Best regards,

Viktor Krammer
