It's possible that in a post-Catalina Mac world, Unix scripting languages -- at least the ones currently included with the system, e.g., Ruby, Python, Perl -- that Apple will use the same mechanism that they currently use for git and some XCode-specific command line utilities: when you type the command, you'll be told the application isn't installed and it'll offer to download it for you. Even if that doesn't come to pass, I'm not super concerned about this. Which isn't to say that I'm serenely unconcerned, but as people have noted, there are ways to install and manage these without them being provided by the OS vendor, and probably most Mac users here have been doing just that for a long time.
