Well, I started out believing that the current behavior was for the
best, and then completely reversed my position and favored the OP's
proposal. Nothing has really happened since then to change my mind,
so I guess I'm still in that camp. But do we have any new data
points? Have any beta-testers tested this and what do they think?
The only non-developer (i.e. person not living in an ivory tower) who
has weighed in here is Tels, who favored reversing the original
decision and adopting Tsunakawa-san's position, and that was 2 months
ago.

I am pretty reluctant to tinker with this at this late date and in the
face of several opposing votes, but I do think that we bet on the
wrong horse.
