Maybe one day you can shun the darkness and embrace emacs ;) all your problems disappear on that day
I'm not saying emacs and vim aren't really cool technologies. But why would a person who cares about optimizing keystrokes and crafting macros dismiss a tool that optimizes debugging and refactoring? I spend a heck of a lot more time staring at code than I do typing it, and if the reverse is true for you then you're some kind of savant and/or (more likely) you're writing too much code and reading too little of it.
Emacs takes a day to master? Awesome!
Integration has a lot of benefits like tell you the inference of intermediate types. "Don't care about good integration" isn't really advice.
It's like people who brag about syntax highlighting. The 99.9% rest of us consider it a good tool that improves our workflow.
Your options are to wait for it to improve, fix it yourself, or change your tools/workflow.
Some people seem to have had an allergic reaction to my comment. Maybe it's the emacs mention, which was tongue in cheek. Oh well ¯\_(ツ)_/¯ I'll leave it as it is... for this is a righteous battle!
You mentioned Emacs as a solution which has a Rust plugin that has problems like most other Rust tooling. Yes, Rust's tooling landscape is immature and still a work in progress.
Obviously you can just forgo editor integration all together. But you can do that in any editor.
