If you can't keep a backlog stable for a few weeks then you aren't doing project work you're on support or firefighting. Scrum is all about IT project work, Kanban is a more general "efficiently get a pile of tasks done" process which can apply to small IT tasks or building a car.

Depends where you are in your product lifecycle. Pre-product market fit, it's often a bad idea to build and keep a stable backlog a few weeks in length.
