Best practice wrt links and archive.org

I notice that the URL field suggests replacing links with archive.org etc, and I'm wondering if anyone has context on that design choice or suggested best practice.

The most obvious use-case, I imagine, is to perhaps link to problematic sources without indirectly supporting them?

Although, I also wondered if instead was to be more resistant to link-rot, but in that case, I'd worry about depriving "good" sites of support. Not to mention increasing the fallout if one of those archival sites goes down, so I guess this most likely isn't the motivation, but wanted to check.
