At my previous workplace, we were developing a greenfield project, years in the making and kinda already brownish. Our managers were using our estimates to choose the right amount of work to fit into a sprint (fortnight).

Am I misinterpreting things or there is no overlap with the circumstances argued in the OP? Also, in that case, how do we make quality tradeoffs when all features are necessary for the end product?
