Yes, a best practice, but is it The Best practice? Somehow, by definition, I expect the superlative to apply to only one of each.

The mention of legality is my private in-joke. So many laws here (and I guess elsewhere) were written in the last decades, where the standards were removed and replaced with "adherence to best practice" which is then not defined anywhere. Which then creates a no-man's land where anything goes.
