Having said that, here's the reality of bugs that are assigned to a team. Feature work comes first. The (older) engineers don't want this — they want to fix bugs, refactor code, get rid of tech debt. But ever since Jobs returned to Apple, it's become top-down and the engineers are no longer driving the ship. Management want the features.
So, the slippery part is this: once you defer a bug for an OS release and ship your product, deferring that bug in the next OS is a no-brainer. You already shipped with the bug, why is it so important this time around? So users/devs learn to work around the bug.
Occasionally, as an old-timer, I would on a whim just fix an arbitrary bug that was "bugging" me. Sadly though, the process had become so top-down though that I would also need: 1) someone to code-review the changes (and so already you are encountering your first obstacle requiring "buy in") and then 2) get permission from "management" (this might be the BRB, bug review board) in order to submit the fix and the Radar. (There are periods though when they are lax and bugs can be submitted with little justification — or we would just make up some bullshit to get the bug fix in).
I recall the early days with fondness when a dev just checked fixes in.
Me: Craig, are you working on the Crop tool in Photos?
Craig: Yeah, why?
Me: How does it pick the default for whether to use Portrait or Landscape? Half the time I think the default it picks is wrong. Why not look at the image bounds and default to Landscape if it is wider than it is tall?
Craig: Good idea. I'll make the change now and write a Radar for it later.
Also, a shout out to Brendan who would push back when in a feature meeting with something like, "Okay, which of these features can we drop? Because we have some serious technical debt we need to address that was not own your feature list."
