I frequently come across posts as old as 2016 or earlier that have big yellow migration notice boxes stuck at their bottom.

This question came from our P, Q, and R site for A, B and C.

These migration notices help out the people at the time the question was migrated, but I believe they lose their value after a few days (say one week). For example, I don't think that if I'm searching for the decomposition of calcium carbonate in 2018, before showing me the answers, I first must be told that the post was migrated two years earlier...

Of course, I can always ignore it and continue on reading the answers ... but that's not my point. My point is that the migration notice has served its purpose after a certain time threshold, and should be removed after that.

I have seen "Bumped by Community Users" notices go away within a day or two after they've served their purpose. Then what is the rationale behind retaining post migration notices for years? Why not remove them after a certain time threshold?

(obvious clarification: the associated migration event should still be retained within the post's timeline)
