Yes. Maybe some more concrete examples would help: 1) I built one company infra. At first, I figured out what software, servers, etc there was, documented it, upgraded various software, migrated email, etc. I was fired for some nonsense reason, but anyway, we are still friends. 2) I was doing some coding at some another company. Coding did not progress well, so they fired me. Good, it's OK for me. 3) I built Open Source software for many years. Maintaining, merging pull requests, etc. Adding new features, dependencies, etc. When adding each feature, fixing corner cases, so it all works together, many parts are intendependent of each other. Now I'm thinking which dependencies are not deprecated yet, is it possible to figure out how to upgrade all dependencies and upgrade to newest version of web framework. Or should I just figure out how to take in-use code, figure out what newest dependencies there is available, and rebuild whole stack again.
