I've been using pedalboard to manipulate voices for https://github.com/jason-kane/coh_npc_voices/ (TTS for game characters) and it is a very easy library to use/integrate. Kudos to the Spotify team.
If you want to write javascript, use javascript. There are ways to get what you're asking for depending on your use case. types.SimpleNamespace in the standard library provides one approach.
"There should be one-- and preferably only one --obvious way to do it." (zen of python)
I do agree that python logging is a weak point. It is too easy to do it wrong -- particularly when you are a few modules deep.
Two reasons seem obvious. F-strings are relatively new -- the code is maturing and the edge cases are being filled in. Second, everyone can't be working on the GIL and start-up times. There is a tipping point at a relatively low head count where adding developers decreases productivity.
