I'm mainly considering future integration issues. If we define
shape-inside independent of exclusions, then we add in exclusions, we will
have to define the interaction between an element's shape-inside behavior
and its wrapping context. I'd rather hold off on shape-inside until we can
have a single description of how these two contributions to an element's
"content doesn't flow here" behave.
