This all makes eminently good sense; thank you for the explanation. I have updated the comments at the head of the file and uploaded a new version, which is now at http://www.sqlite.org/contrib/download/extension-functions.c?get=25. Nothing in the code has changed, so there's no reason to download the new version if you already have the old file.
