Your point about interoperability is probably a better expression about what I had in mind. Whenever there is a new advance in algorithms, at least all languages should benefit from the “reference implementation”, be it C-FFI (the current story - write in C first and everyone wraps) or something like WebAssembly. Then when a fancier/more idiomatic one is available, use that. Current story with the C library path is so hard to use in practice.
