Looks good, technically you still got the flags as package global but they're much better organized and accessed now. You could probably even move the flag var declarations into the first lines of main to make them fully private but that's just my take on it.

Yeah, you absolutely right. This pr is mostly of making tests more testable (like t.Parallel if needed), but I fully agree that moving flags to main would be a better idea, but if we will do that in all commands we will got a test coverage hit. So we either need to introduce some kind of parseFlags function or give up a bit on test coverage.
