Paul -

This issue has bubbled up from time to time over the last 18 months or so (judging from my email archives).  It is not at all clear to me that there is indeed a "consensus from deployments"; some like it, some don't.  We tend to (unsurprisingly) hear little or nothing from the people who think it's working just fine, and it is very easy for a local group in which a few folks think the behavior is wrong to quickly collectively conclude that it's wrong.  We've deployed hundreds of thousands of machines since this change, and I don't think we've seen hundreds of thousands of complaints.

I don't have a strong opinion and I don't know the answer, but we should be very careful about ignoring the silent majority, if there is one.
