@schlunma could you pls have a look at the complaint in the failed test and implement the new method, when you have a minute, pls, bud 🍺 Let me know if you busy, I can get a PR done with that 👍

Those diagnostics and the associated recipes are actually good candidates for the legacy recipe directory. The only problem here is that one of the diagnostics is used in one other recipe, but I will try to sort that out.
