You mentioned a declarative package manager for Mac. I've really liked using Homebrew Bundle [1] over the last couple years. It's about the level of declarative that I've wanted and has made it really easy to bootstrap new laptop or VM (since it also works on Linux). The format for a Brewfile was pretty easy to figure out.

The way I ended up using it was that `brew install` would temporarily install something, without adding it to my Brewfile. And a little `brew add` wrapper would add the package to my Brewfile to keep it on the system permanently. That part with the wrapper could have used some love and would be a nice fit for a new brew-compatible frontend IMO. Maybe you could expand on that for Sapphire, if that also scratches your declarative itch?

That would be fantastic. My bootstrap scripts already use bundle but it’s easy to fall into config drift.
