What does "We're unable to work on your request" mean?

A multitude of Feedback items were closed over the weekend (Oct 26th) with the only Admin comment being "We're unable to work on your request." That statement begs the obvious question: why not?

The speculative answers that come to mind are not very positive for Yahoo Groups as a product (the development staff has been let go or re-assigned; we couldn't understand the request and didn't care enough to ask for clarification; we've suffered an overwhelming technical difficulty; ...).

Rather than invite speculation, it would be helpful if Yahoo could give better responses to these items.

If the inability is "at this time" then perhaps the items should be given a status that leaves them open rather than stating that the issue will never be resolved.
