The main issue here is that the Fish project wants to own auto-completions for ripgrep, and generally speaking, I don't want to stop them. In particular, ripgrep's Fish auto-completions are auto-generated by Clap (ripgrep's argv parser). I have no idea how good they are, but they are only provided by ripgrep because it's easy to provide them. Otherwise, I would not maintain them.

The actual reason to drop them is that they are causing problems. See #1485 and fish-shell/fish-shell#6868 in particular.

The plan here is:

• The ripgrep 12.1.0 release will include a notice that the Fish shell completions will be dropped from the next major version release.
• The ripgrep 13.0.0 release will drop Fish shell completions.
• The Fish project should be notified once the ripgrep 13 release is out so that they can merge ripgrep auto-completions as they see fit.
