Uninstalling Homebrew

So i just uninstalled homebrew and I assumed it uninstalled all packages and etc. but i got this following prompt at the end of uninstallation:
> Homebrew uninstalled!

The following possible Homebrew files were not deleted:

/usr/local/.com.apple.installer.keep

/usr/local/libexec/

/usr/local/share/

You may wish to remove them yourself.

I just want to know if these files can be deleted because I am not too familiar with these types of things. Also if they can be deleted how to go about doing so. Thank you.

You could just go to /usr/local in Finder and remove them. If it’s in the list of items it didn’t remove then it’s because it couldn’t. So Homebrew thinks they’re safe to remove
