Yes.

Yes.  But that's still not a prohibition; the standard merely refrains
from defining the behavior.  The way the standard phrases it is that "An
object shall have its stored value accessed only by an lvalue expression
that has one of the following types", followed by a list of types (N1570
6.5p7).  The "shall" outside a constraint means that the behavior is
undefined -- i.e., the standard imposes no requirements.

You make some interesting points, but if your goal is to suggest changes
to the standard, I suggest using the standard's terminology as much as
possible.
