As a lead dev I have plenty of cases where I weigh effort vs impact and risk and conclude to "this is good enough for now". Such cases are not poor management - which I assume you mean something like "we have to ship more faster, so do the shortest". Sometimes cutting corners is the correct and good decision, sometimes the only feasible one, as long as you're aware and weigh risks and consequences.
We, and specifically I, do plenty of improvements where possible and reasonable. Whatever I visit, depending on how much effort it is. But sometimes effort is too much to be resolvable or investable.
For context, I'm working on a project that has been running for 20 years.
