+- [#7134](https://github.com/thanos-io/thanos/pull/7134) Store, Compact: Revert the recursive block listing mechanism introduced in https://github.com/thanos-io/thanos/pull/6474 and use the same strategy as in 0.31. Introduce a `--block-discovery-strategy` flag to control the listing strategy so that a recursive lister can still be used if the tradeoff of slower but cheaper discovery is preferred.
