And the people using it multiple times a year delete it afterwards?
To step outside just utility programs, the reason why Command & Conquer didn't have a remaster was:
> I'm not going to get into this conversation, but I feel this needs to be answered. During this project of getting the games on Steam, no source code from any legacy games showed up in the archives.
The people wouldn't, but in the environments I'm thinking of, security policies might.
What you're leaning into is a high-risk backup strategy that would rely mostly on luck to get something remotely close to the current version back online. It's pretty reckless.
In environments that go so far (deleting local checkouts of code out of security concerns), I bet they do have a mirror/copy of the version controlled code.
