Switched to cargo and wg-diagnostics :+1:

[Kobzol]

I saw you removed me as explicitly having write permissions as I am under cargo and I am fine with this for now, but if cargo is ever removed, I will need to be added explicitly.

Yeah, that's not a problem, we can change the permissions quite quickly if needed.

I think that it's just waiting for a merge :)
