This extremely useful feature, which is sometimes called "picking", has
been discussed extensively on the group, but the "thought leaders" (?) who
apparently have the ability to kill a feature by saying "I don't really
think it's that important" have failed to get excited about it, although it
seems to me to be at least as "interesting" (in terms of the unwritten
criteria apparently applied to determine "interesting") as many other
features which are progressing through the ES39 life-cycle, and the nature
of the TC39 governance process, which gives entirely new meaning to the
notion of "design by committee", makes it impossible to find the champion
which is the gating factor for the entire process.
