Oh wow, this seems like a fantastic addition. One of these days I really gotta switch from my decade old tmux workflow to zellij!

I can somewhat relate. I mostly do something like this (instead of the exact dependency version):

chrono = {version = "0", features = ["serde"]}
clap = {version = "4", features = ["derive"]}
anyhow = "1"

I do, however, typically write application code instead of library, so it's probably less critical for me. Occasionally do run into dependency hell here and there, but nothing too bad so far!

A few things:

• Instances are like their own self-hosted Reddits with communities being the sub-reddits. We have (had?) r/python, r/rust, r/golang along with r/programming; we can do the same here with topic-focused instance (like this one). I can imagine there being instances like lemmygo.org, lemmypy.org etc if the Reddit exodus continues.
• You don't need multiple accounts to access communities (sub-reddits) from other instances (reddit). A single account on any instance allows you to access communities from any other instance. The UX/UI is a bit wonky, but it works.
• As @erlend_sh@lemmyrs.org pointed out, micro-communities like cli, wasm, networking etc can potentially become big enough and/or have specifics that are more suitable to exist on a topic-based instance.

Personally, I don't have any preference. I will simply subscribe to the community which is the most active on whichever instance.
