@paleolimbot I'm curious about this in the method docstrings:
```c++
/// For statistics read from a Parquet file, dimension_empty() will always
contain
/// false values because there is no mechanism to communicate an empty
interval
/// in the Thrift metadata.
```
Why was it done that way, if emptiness is a useful information to have? And
is there a point in exposing emptiness in our geostats APIs? Usually, people
want to filter from a Parquet file read from disk, not one that is being
constructed in-memory...
