I thought this would take **kwargs and just set whatever keyword argument(s) is/are provided on all of the DOMNodes. Wouldn't that be more helpful than being prescriptive about the specific attributes we can set?

It's for the benefit of typechecking mainly.

disabled and loading are attributes on widgets, not on DOM nodes. Won't that be a problem? Maybe due to typing issues or inconsistencies?

Can't this be defined outside of the for loop?

Why not partial(setattr, self, variable_name)?
Bit of a mixed bag. Added a number of things while working on Tailless. The most notable is probably the data binding.
See changelog for details.
