Dave,

If I understand you (now more correctly): because byte packing is
default, you want a vanilla cast (without __packed prefix) to be
treated as byte packed cast.

How would a programmer then indicate a cast to a vanilla (not packed)
pointer?

If the compiler always assumes byte packed no matter what, arguably
the compiler cannot take advantage of the faster method of dealing
with composite objects.
