I do think they are useful to me, but I don't know what the percentages of folks who want them vs. not are, and whether people have actually tried multiple schemes.
I think it's more likely that we get bug reports to put them in if we don't show them than the other way round, so I think taking them out is a good way to get that feedback :)
