All you got to do is create your own full form.pt and register the macros in
order to have hooks. You can even leave out all the macro registrations.

This is overcomplicated. If I remember correctly, you can do:
<tal:block define="widget view/widgets/mywidget">
<span metal:use-macro="macro:snippet" />
Also, if you do not like macros, you can register simple views to have:
<span replace="structure view/widgets/mywidget/foo" />
For me the cost of the snippet is too high:
1. It introduces a new pattern for cases that are well-covered otherwise.
2. It requires a new directive.
But as I said before, you should publish your work and see how people like it.
