That's correct. It shouldn't be too hard to add support for it,
but it has a might be problematic for us to enable, because in
some parts we may incorrectly implement the IDL vs. application
layer encoding and may not be compatible with clients, e.g. with
spoolss. Maybe we need to make the support ndr interface specific
and whitelist interfaces we have verified to be usable with ndr64.
On the other hand I don't think the ndr32 alignment has any practical
performance impact. There are no performance critical rpc interfaces.
