I’ve read through that thread before, which is really about separating current Ideas posts, i.e. proposals to making changes to Python, based on bakedness, and the problem there is that it’s always highly subjective how baked an idea is. So we continue to have Ideas posts that range from a 1-sentence wish to a fully fleshed out proposal+reference implementation, which I now think is OK.
What I’m proposing here instead is to have a separate category for ideas not based on bakedness, but based on whether changes to Python are involved.
While there may still be arguments later in a “project incubator” thread in the reverse direction about whether it should be moved to Ideas because maybe a syntax change would better serve the purpose, at least from the get go the OP has a place to frame the idea as a third-party library.
