I've used Fish for many years, but frankly only for the great autocompletion. The streamlined theme/prompt system and oh-my-fish plugin management are quite nice too, but minor.

The rest of Fish features that are not bash-compatible are rather a pain, particularly environment variable management. In principle these features have a better design than in bash, but not that much better, and their use is infrequent enough to have to re-learn them every time. Unfortunately, they just end up being a minor inconvenience when you try to copy-paste setup instructions from docs, and I don't interact with these features otherwise.

The better syntax used to be a selling point, but now with AI being able to generate any trivial one-liner and minor scripts you need on a day-to-day basics, have a bad syntax would only affect bigger projects, which I would not write in Fish shell anyway.

It's a hard sell.

The most interesting thing about Fish 4.0.0 for most people will be that it is now written in Rust, which they talk about here [1]. Looking forward to testing it out and seeing if there are any noticeable differences. [1] https://github.com/fish-shell/fish-shell/pull/9512

I'll be curious if it's faster.

Can someone from the team share how the dev coordination for the Rust migration was handled? I only see a single PR (#9512)—how was the work organized?

I'm surprised Rust took more lines. Perhaps formatter makes shorter lines due to method chaining? Or improved test suite?
