Okay, but that doesn't address the larger questions I asked. The documentation, as written, gives no explanation of the purpose of this option. Since you conceived of the option and implemented it, you implicitly understand its use-case and repercussions which might arise from using it, but is the typical reader going to understand all that? Namely, is the reader going to understand: * why this option exists * what problem it is trying to solve * when to use it * when not to use it * what the repercussions are of not computing a hash for the index * etc. Are the answers to those questions documented somewhere? If so, then the documentation for this option should link to that discussion (and vice-versa). If not, then those questions should be answered by this documentation.
