First I've heard about issue with bash.

I've been using OhMyZsh in all terminals for years which seems pretty active and auto updates fine whereever I'm using it, e.g in Linux, macOS, Windows/WSL. Zsh might have a slower release cadence but I'm really happy with my with Oh My Zsh setup and don't feel like I'm missing anything.

The one area where I've stopped using bash/shell is in complex shell scripts which I'm now writing in TypeScript and executing with Bun by using: #! /usr/bin/env bun
