Best way to have language-specific sorting comparators?

[andbleo]

I like the current defaults for how sorting works, except in Rust. What is the best way to change the sorting comparators just for Rust?
Would it make sense to make a Rust-specific ftplugin where I replace the comparators list, similar to what is shown here: #666 (comment)
If that is the right way of doing this, do I need to worry about reloading the default comparators list for all other languages if I change to a buffer for a non-Rust language without restarting neovim?
