gcc48: remove by tobim · Pull Request #256328 · NixOS/nixpkgs · GitHub proposes to remove GCC 4.8, and I’d like to invite you to post you opinion if this might cause problems for you. It would be great to learn whether this package is currently used anywhere.
I use old versions of gcc from nixpkgs for testing software. Some vendors in the embedded space use ancient versions of gcc, and having them in Nix helps me reproduce issues, so I would be sad to see it go. However, if it a maintainance burden, I would understand removing it.
Maybe worth a gander at https://github.com/search?q=language%3Anix+gcc48+-path%3A**%2Fpkgs%2F**&type=code as well.
