Yes on all except 1360, 1573, and 2140 for reasons noted below.

It is not clear whether the single assignment rule
follows exactly the same longest static prefix rules
defined for the sensitivity analysis.  I think it
does but that should be stated explicitly.

The new text says:
    An input port is used as an output or inout if it is
    assigned a value within the module...
But what about a hierarchical reference from outside
that writes to the port?  That also "coerces" the
port.

I think that Steven's comments regarding confusion between
coercion and collapsing are in play here.  I think that
the new text makes things worse be saying "shall" and by
missing various non-local effects including hierarchical
references and pli at the least.

I think we need much more discussion on macros before
making this decision.
