Let's be clear here: that is not some random implementor's decision.
That is *necessary*, else the feature is completely insecure.

The example given at the top of the thread isn't especially
security-relevant, but there are a lot of other possible ALTER commands
that are. For example, an ordinary user granted ownership of a
"C"-language function can easily modify it in a way that allows her to
gain full control of the installation. So we cannot implement trusted
extensions by allowing the user requesting the install to own the
individual objects within the extension.
