I agree it's complicated, but all the complications and options already
exist - they're just split across two similar-but-not-quite-identical sets
of data types.

Not sure what you mean here. We know that whatever object a returns is
going to have scalar behaviour. Right now we have two totally different
implementations of scalars. I'm not suggesting changing any (or hardly any)
existing behaviour, just that we switch which implementation of that
behavior we use.
I actually wrote that email as kind of amusing exercise in "what if...?",
but even after sleeping on it I'm still not thinking of any terrible
