Remove graph-wrapper

[soenkehahn]

I don't wish to actively maintain the package anymore (see also here) and I was pinged in #7549 about it. Is removing it from the file the best choice here, since it doesn't build with ghc-9.10? Or should it be moved to the Grandfathered dependencies instead?

Thanks!

Thank you for the kind request. Generally moving to Grandfathered dependencies is the preferred way (since this allows the package to stay in the index until it really needs to move out (because of outdated dependencies or build failures)). However, since no further packages are affected and because we plan to switch to ghc-9.10 soon I think it is fine to directly remove graph-wrapper now (the only real visible difference is that this way the package wouldn't make it into lts-23 for ghc-9.8).
