Homebrew has continued to improve performance each major version. It's certainly a lot quicker nowadays than 5 years ago. I want reliability and safety in a package manager, speed is nice to have.
I applaud competition, but something like this starts with trust zero as far as I'm concerned. If there is one place that I want human input over LLM it's here. It needs to scream: smart humans are in control and overseeing the project. I don't see that here.
