We have core code that uses reloptions --- autovacuum for instance ---
so I'm not exactly clear on why that's so unacceptable for this.
If the concern is that the required metadata is going to change over time,
I'd suggest that maybe an extension is the right place for it,
permanently. We have some infrastructure for extension version upgrades,
which could cope with metadata changes. There's not nearly as much
provision for changes of core state.
