You are.
I'm also afraid that with
the extension I'd be left on my own maintaining it forever. While if
this could go into the core product, it would live forever.
This is an argument against ever doing anything as an extension.
You have not at all addressed the real problem with doing what you are
asking for, the one that Tom Lane stated:
Basically, there is zero chance this will happen unless you can find
a way of fitting them into the numeric promotion hierarchy that doesn't
break a lot of existing applications. We have looked at this more than
once, if memory serves, and failed to come up with a workable design
that didn't seem to violate the POLA.
