Nice plan. I think it is no big deal to change them with bot. Templating is the usual and maintainable way.

Sorry, no, within the German WP templating within flow-text is usually a no-go. And with the advent of lua templating isn't maintable as easy as it used to be. (ceterum censeo: lua is bad, really bad for usability by normal users)
People need to understand a load more to use the templates, than just type "ISBN blah" . I don't have an issue with RFC being demagiced since its a speciality item. But for ISBN this is a stupid move. Rich Farmbrough 08:19, 8 June 2017 (UTC).
