What to do about list values in LazyMergedMapViews?

I don't know what to do about these, there is no obvious answer.

For now I am adding a check that they have the same length, and just returning the left one, but that is pretty clearly flawed.

I think we'll anyway need to revisit how we handle the data for merging, so this can be part of that.

We could return a list wrapper that knows both lists and lazily checks for equality :)

An entirely different approach would be to only send differences to previous query results, so that there are never duplicates in the merge.

The problem is we don't even have well defined equality.... if we have a list of Map objects, which are each incomplete model representations....
