I'm using alacritty all the time, and I'm thinking of switching to starship from powerline because powerline has noticeable startup time (I think it is python-based). Unfortunately neovim+plugins does too, probably as a result of plugins more than neovim.

I tried this and it is much nippier than my current neovim+plugins setup. I'll have to plug in a bunch more language servers to fully compare.

In a way I'm almost hoping they don't add a plugin system. There's something to be said for this all-rust future my terminal suddenly seems to have found itself in: it is quick!

Alternatively Powerlevel10k[0] makes for a fast powerline implementation, especially with instant prompt enabled.
