Are there packages in Guix that are going to depend on it?

If not, could you explain briefly why we should have it?

In general, we keep old versions if there’s a package depending on it or
if there’s a strong use case (for example, developers may often work
with different versions of Python, GCC, or LLVM, so we keep several
versions of them).
