Yes, but there is a difference. You are a mod author, you know that changing the toc number doesn't actually fix anything that is wrong. And you have an idea of what you are doing to be able to fix it, if the original author doesn't update. That isn't saying that the average joe-mod-user is stupid, just that the average joe-mod-user isn't a programmer and doesn't know the ins and outs of fixing code. For the average joe-mod-user, changing the toc number themselves just means that when something is actually broken, they don't know why they are suddenly getting error messages, since as far as their WoW is concerned, all the mods are up-to-date. If on the other hand, they don't change the toc number, if they start getting error messages, they can look at their listing and go "oh, okay, this mod hasn't been updated yet, it's probably the one causing the problem" and they go look for updates. So, telling the average joe-mod-user to update their toc numbers is a Bad Idea™.
