Review Comment:
`removeSnapshotsIf()` uses a `Builder`... so why rebuild twice? Why not
inline the code from `metadata.removeSnapshotsIf()` and reuse the same builder
both for filtering and resetting metadata location?
I guess it's also going to be more efficient by _not_ constructing two
useless lists: `List<Snapshot>` and `Set<Long>` 🤔
