You can say it about every python feature. Using a new feature restricts you to the latest python version. Eventually it will trickle down. > The fact that it wasn’t there from the start like GCD’s default queues > were means people have already come up with other solutions and they might > not want a different one. > There are no other solutions to that problem. Up until now, people created their own solutions, and their own threads, out of necessity. They simply didn't have a choice. I've witnessed a large project which used many 3rd party packages, and had no less than 148 (!!!) threads, since every package had to create it's own thread, waiting in the background and doing nothing. Since I'm a backend developer, I can see it being highly used in my field. Metrics? Server statistics? Lot's of times it's a fire-and-forget mechanism, that just needs to execute stuff in the background. But heck, even using logging.QueueListener creates an unavoidable thread. Right now there's no standardized way to do so. I thought of concurrent.futures with a get_global_pool() as a simple solution, but did not know about GCD. We can try and implement something equivalent on a provisional basis, that newer packages will use. There's no need to port older code to use it, as it will slowly fade away. > once it goes into the stdlib, its interface is fixed forever. Well, it just means we have some thinking to do. Rome wasn't built in a day. With all the benefits of creating a PyPi package, I'm afraid adoption rate won't be high if it won't be a standard. The solution to the issue can either be starting with stdlib on provisional, or developing and releasing under a well known developer's name, much like PyPa or aio-libs. These questions are eventually up for discussion. I'm just a single developer with a small perspective, and don't pretend to know the answer :-) Perhaps more devs will weigh in and give their opinion. Always happy to learn, Bar Harel.
