Really, it was my mistake to ever make you think that context_var.assign(42).__enter__() can be compared to .set(42) in PEP
Then your alternate PEP can't work, since it won't be useful to extension modules.
Context managers are merely syntactic sugar for try/finally statements, so you can't wave your hands and say a context manager is the only supported API: you have to break the semantics down and explain what the try/finally equivalent looks like.
