Glad if it's working now regardless though, I also see some experimental support for coverage in the docs now.
I do wish some of this stuff would be documented better. I find Node's documentation to be some of the worst for never being able to answer the specific question I have when I'm reading it — IIRC I was also unsure whether the type stripping thing would work for a monorepo, and the closest confirmation I could find online was a comment in a PR somewhere that implied it ought to work, but nothing more specific.
