Feature Request: Infinite layers

I think something this might have been suggested many years ago, but nothing came of it:

I occasionally add something such as a ‘corner bug’, a safe zone, etc. on a comp that I want to just sit there for the entire duration of the comp. If I extend the duration of the comp, it’d be nice if I could set this layer to be an ‘infinite layer’ (infinite in time). That way, if my comp was 10secs long, and I then added this layer, I could then set it to be ‘infinite’, so if I then extend the comp to 20secs, the layer will automagically extend until the end of the comp.

I propose this would be an option that would sit under ‘Guide Layer’ in the right-click menu. An icon, next to the Guide Layer icon, could then appear to show that it’s an Infinite Layer. Maybe a stopwatch icon? Or an infinity symbol?
