Ok.  Thanks a lot for providing a data point.  This helps.

which really bothers me. We should at the very least turn this off by 
default, and work toward deprecating this in the future (as Eike also 
pointed out).

Any objection to that?  Anyone?

Not currently, but the named range can be expanded to add that capability.

Having said that, the expansion of a range sounds more fit for a 
database range than a named range.  I'm now more leaning toward database 
range as a possible replacement for the labeled range feature.

Good point.  If we don't do this currently with named or database 
ranges, we can add this capability to cover this use case.

Probably not. But if/when we implement enhanced database range, this use 
case will likely be covered.

This helps, as I was also looking for the missing pieces that the 
labeled range provides, so that we can cover those missing pieces in the 
other existing range features by extending them.  Looks like it's 
plausible to extend the database range to cover these missing pieces.

Thanks a lot for your feedback.
