Yes, the factors to consider include:

- cost of the effort

- probability of success

- trade-offs in the case of success or of failure

This kind of bit rot is somewhere (often everywhere) in many fast-moving businesses, as a natural consequence of the value tradeoffs we have had up to now. Now there are machines that can speedrun the grunt work of clearing them.
