Yeah, and there’s plenty of potential spoilers in those files too. It’s unfortunately pretty difficult (and often literally impossible) to prevent players from digging out information like it.
I think the best bet is for the community to be open about the information that they dig up - that way everyone can benefit, rather than some “elite” few that are in the know. Optimistic, I know 
This works pretty well in most communities, though (see wowhead.com for WoW, etc).
If the game stores something on your disk, or in memory, an enterprising player will always be able to (eventually) gain access to it. At best, the devs can try to make that process more difficult (via encryption, or obfuscation). It’s a losing battle, and not really worth the effort (especially for a small dev studio).
For these specific settings, I suspect that they don’t really need to be included with the steam-bundled game, since the server is the one operating against them. (But not worth the effort of hiding from players, …yet) So, resource regeneration config may actually be one of the few game systems that can be hidden from us players.
