I somehow thought that it was a policy decision we made in very
early days that these conflict messages are meant to be edited with
explanation of how they were resolved, not to be simply edited away?

The other stuff (commented out instructions and patch text) are
meant to aid humans while editing the log message, and stripping
away automatically after they are done editing like your patch does
is perfectly fine, but I find this change questionable.
