It sounds to me like we're creating a JSON format for the DOM and
making element.append accept the JSON format. This doesn't sound great
to me. It basically sounds like too high level to fit enough use
cases.

It seems better to have an API for creating a single element (with
attributes and event handlers), and then let people combine calls to
that to do their own JSON->DOM conversion.

Possibly it would make sense for the function to take an additional
string-argument is used to create a text node which is inserted as a
child. But I don't think we should add complexity in the form of
sometimes interpreting that string as a node-name and sometimes as a
textnode value.
