Why bother with the None? Let's just pass None directly to read_any and make everything else simpler.

Behind the hood, this is going to open each metastore file and then fetch the split stats sequentially, which is going to be slow if there are many indexes. Try to parallelize this logic using FuturesUnordered. There are examples in the file.
