Yes but it is basic in the sense that it’s one of the first couple algorithms/data structs mostly everyone has been exposed to. Many knowing what they are and the general principle of how and why they work. That is exactly my point though.. Like what do we consider “basic” exactly? That line becomes blurry in any complex field…

If you don't use something, you forget it. Nobody is writing these algorithms in their job. If you did, it will get flagged in code review, the same way rolling your own crypto does. Which is why I think it's unreasonable to expect people to remember how to implement them off the top of their head.
