The [[DFSIndex]] field of module records is only ever read by `InnerModule*` algorithms, and only on the same module that the algorithm is called on. There is no need to have it as a field on the module record, and removing it helps by having on less piece of potentially mutable state to keep track of while reading the algorithms.
