This is not something that was done to make life easier for developers. 

disable-output-escaping is bad because it violates an architectural
boundary, it means that the interface between the transformer and the
serializer is not just a document (as an instance of the data model) and a
set of serialization parameters, but a document plus a single bit per
character that says whether escaping should be disabled. It's not developers
who suffer when architectural boundaries are violated, it's users, because
it means that your code is less reusable and your applications have less
potential for change.
