Design Pattern: Using Item Metadata as an Alternative to Several DPs

Speaking of listening for changes, another idea I had here was if it is possible to trigger a Rule based on changes to metadata.

I do not see any RegistryChangeListener implemented in OHC, which I believe means that nothing is listening to metadata changes. Jython could definitely be used as a sandbox for this, before implementing in Java. This would be an interesting feature for OH3.
