Other than the fact that we'd feel free to change the behavior of any or
all of that with no notice?
aclitem is an internal type. If you depend on its behavior, you'll have
only yourself to blame if your application fails in the future.
(I probably wouldn't bother making this point, if the immediately
preceding message hadn't been from someone whining because we changed
the behavior of hashname() ...)
