Frustration often comes with extensibility: adding extensions on top of VSCode that need to run at file save time (eg: formatters) can lead to pretty significant performance drops.

This extensibility is probably what made VSCode popular though, especially for web devs since the extension mechanism is JavaScript-based.

Makes me wonder if those Rust-based tools (Lapce, Zed) will have as much success with Rust-based extensions authoring.
