Yep. In our case we were using it for scheduling purposes and "Who is free on thursday at 2pm?" and we got very little narrowing because most people are available at least some time in the morning and some time in the evening. We've loosely landed at just materializing the dataset into another table by calling `unnest` in a trigger and then using an index on that table.
