Homebrew Fallback

[ProfessorManhattan]

Hey, I'm interested in using this to handle installations for various distros for https://install.doctor. However, I have a few questions.

1. Is there a way to use fallback install sources? For instance, on Ubuntu I'd like to use apt and then fallback to brew if the package is not available on apt.
2. How should we handle cases where the apt package is named differently than the brew package etc. If I use this, I plan on incorporating software installers like Flatpak which has different names than other things (i.e. io.github.Client for example). Does there exist any open database that maps out all the different official package names for each item?
3. Any chance you can add support for Windows by including Chocolatey / scoop.sh / winget support?
