The leading _ does indicate that the method is intended for GS internal 
use only ... we do not guarantee that _ methods will be present in 
future versions of the product ... with that said, I don't think there 
are any plans to remove the selector in the future, but I can't make any 

Sending #indexSpec to an UnorderedCollection will return an empty index 
spec if there are no indexes on the collection. So `coll indexSpec specs 
isEmpty` is probably the best route for the long term. And one could 
argue that we should implement isEmpty in GsIndexSpec ... One could also 
argue that we should implement a public hasIndexes.

To help with these arguments, what is your use case for needing _hasIndexes?
