Hello Scott.

I think most likely explanation is nobody is using this feature for any 
real analysis work - nobody noticed.

We are currently stretched pretty thin. I suggest you open support 
ticket if you are a support customer, or open a public issue in case you 
are not.

That way it will be at least tracked.
