That's what spoiler tags are for. But avoiding confusion with other mods and vanilla is very much a good idea, and to do that, you need to at least make the information available. People can decide to look, or not, as they like; but it's simply good manners to explain what your mod does.
Otherwise, you're making more work for Alex and for the rest of us; we have to tell people it's not us, all of us, when you could just explain that a given condition is yours, right in the mod thread, like a good citizen of the community would.
