True. That may be a good idea to think about it from this angle, I
totally agree.

I guess not. There were some flaws in how HTML handles scripts, namely
(among others) unconditional execution of inline scripts and
unconditional execution of scripts whichever there source is. Both could
lead to XSS as we know.
Since the flaws couldn't be fixed at the content level, they've been
fixed at a lower-level (CSP). It might be where to find the solution.

Assuming every set of frame is a tree, maybe an HTML attribute could
define a script source which defines a module loader for how modules are
being imported in the iframe?
