I mean, isn't that how package managers work too? Just relying on the default repo of each one, since most users won't work with new sources.

Or, I can just not use a program like chocolatey and just go one and done on ninite. Heaven forbid they only have apps on there to choose from that are popular and people want to install. I've never had issues with any of the programs being behind on version, but it isn't like each program can't check for newer versions of itself

The great thing about ninite is how you can go there ahead of time and generate a single file, and when you're done installing you just run that file. I suppose one could generate a batch script that installs stuff with some other package manager (you'd need to include install/update for it first, I remember reading about how Winget can come outdated with a broken version), but the issue with that is simply that ninite definitively exists and works reliably, while I don't know any such service to generate install scripts.
