Additionally, I'd love to see the PR where this change was implemented. I've been trying to convince Zola, a static site generator written in Rust, to support older versions of GLIBC.
Most of the code is here. It needs some linker config but basically you wrap symbols which depend on too new versions of glibc and dynamically load them or call some other implementation internally
