Yes, it's do-able. As others have pointed out, nvm also works. 1. There isn't nvm for things that aren't node. Some things have an equivalent (e.g., pyenv). Many external dependencies do not. 2. I've inherited a spiderweb of like two dozen different major projects that are all interconnected. Doing an upgrade across everything at once means a stop-work for months while all the developers update tooling, then fix all their issues so everything works, then we try and coordinate testing and deploys of everything without breaking anything. Or, alternatively: 1. We don't need extra tooling that doesn't exist. 2. We can update projects one at a time instead of mass-migrating several million lines of code across half a dozen different frameworks.
