Never assume. Apple engineers have told me stories about glaring bugs that I assumed were obvious but had a grand total of one report ever filed against them, years after the bug had been introduced.
That said, I don’t file every bug I encounter with the OS (particularly things that have seen obvious changes over time, like the WindowServer in Yosemite), but I do file a lot of framework bugs.
