Python 3.11 in the Web Browser
I really, really wish it were possible for wasm modules like this to be shared between sites. That is, python.org could host an official wasm module, and the first time you visited a site using python the browser would download and compile it once and cache the result, and then any other website could use python with no download size or load time penalty. But unfortunately privacy concerns killed this utopia. Caches are now partitioned per origin, so every site that uses python has to download and compile the wasm module separately even if it's the exact same module from the same place, and that is unlikely to ever change: https://developer.chrome.com/blog/http-cache-partitioning/
