People have different opinions. But the one that counts on this issue is Fencer - and if anyone can get Fencer to work on this feature rather then on the site and/or games - well good luck.
Otherwise, I think it is safe to say that many would like it - some don't care, and probable a few don't want it. Is there anything else we need to say about this?
