True, but how much of a difference? The REGEXP I wrote took almost 10
minutes to do what my LIKE did in 30 seconds. Unless your two hosts are
separated by 300 feet of 802.11 at 2 mbits, I don't see this as an issue.

If we started to rely on is_header in 2.0.1, then if someone downgraded to
2.0.0 for a while, then upgraded again, they would have to re-run the
upgrade script to assign the missing is_header columns. I'm concerned that
this eats into our robustness along a stable series.
