No, you don't have to "care". Presubmit _won't let you_ break them. That's the whole point of presubmit - to make sure tip of tree is green 100% of the time. You can't submit something that breaks the build _or_ breaks the tests. You can work with the code owner to make sure you can commit in the first place, but you don't get to just push your changes through and have the code owner deal with the fallout. Facepalm.
