Yes, it is important.

That was not the feedback I have received. Nobody has commented on that
to me, though many have commented on the need for the current patch. As

feedback and the result was very clear.
Of course, if we ignore any feature, then someone will say "its that
stupid issue again", but that won't imply we got our priority wrong.
