Hi Dave, good question. The same issues as mentioned before still exist. Especially that the keys of dynamic-properties are a runtime information, so we can't create indexes upfront.
Also for derived queries it would not be possible to identify which or if any index to use for the query. Perhaps instead of looking into EmbeddedProperties it would be better to check out embedded entity support (there you could handle variability with subclasses) each of which could have annotations on entities to be indexed.
