So, it would be nice to give a hint in the actual documentation, why a user might use the flag, or for a maintainer to be able to predict exactly what was desired in some obscure corner of dwarf semantics given the documentation. I think it can be as simple as “This option is useful for code coverage tools that utilize the dwarf debug information.” A user, upon seeing that, would then ask, do I have such a tool, say no, and then know they don’t have to contemplate the goodness of the option further. If one is writing a coverage tool, upon seeing the documentation, they might then ask themselves, how might I use that flag profitably for my users.
