I think this is useful as it can make porting easier. I am using it in my attempts to cross compile CPython to WebAssembly (since WebAssembly in its MVP does not support threading).

The problem is that the burden of maintenance falls on us (core CPython developers), while none of us and probably 99.99% of our userbase have absolutely no use for the "functionality".

Perhaps there's a simpler, cruder way to "support" threads-less platforms. For example a Python/thread_nothreads.h where PyThread_start_new_thread() would always fail (and with trivial implementations of locks and TLS keys). But I'm not sure how much it would help those porting attempts.

Antoine.
