@DanielNoord I would put the better primer in 2.13 at least, even 2.14 for false positive detection, what do you think ?

[DanielNoord]

I think we can close this, make quality of life improvements for 2.13 and add false positive detection in 2.14 and beyond. I'll update the 2.13 issue with some other things I thought of!

Done in #5425
