Uncluttering gives reduction of bandwidth anyway, so I do not see much point in the distinction you seem to be making. > Is this what you've been working on?

Nobody seems to have attacked it since it was discussed, and I was tired of hearing nothing but complaints and whines. This "hiding refs" series was done as a cheaper way to solve a related issue, without having to wait for the solution of "delaying advertisement", which is an orthogonal issue.
