   Another option is to have a warning anytime you build on a platform that isn't supported.

   Another option is to have a warning anytime you build on a platform that isn't supported.

   We already have the following code in place:

   https://github.com/python/cpython/blob/5ce193e65a7e6f239337a8c5305895cf8a4d2726/configure.ac#L961C13-L995

   Removing this line...:

   cpython/configure.ac

   Line 982 in 5ce193e

   [wasm32-unknown-emscripten/clang], [PY_SUPPORT_TIER=3], dnl WebAssembly Emscripten

   ... should end up producing a warning.
