AFAIK this just involves adding another row to the table of platforms
with special needs in Mule initialization.  Don't *enforce* the
semantics of "always", because there are exceptions.

What do you mean, we "should" normalize?  Normalization is an
optimization.  We should recognize all equivalent forms as equivalent,
but we can leave the actual normalization to those systems that do
normalization AFAICS.

We should be *able* to normalize for the purpose of communicating with
non-conforming systems, of course, but that is not trivial to
implement portably.
