This is exactly right, but in my opinion usually not important. If Joe Public, or a competitor, or whoever knows how many posts you have, users you have, administrators you have, etc how much does that actually affect your operation? I guess they can better compete against you in some small way with that information, but in my opinion it's almost never worth the effort to obfuscate. It's like optimizing for a problem you don't have.
> how much does that actually affect your operation?
If it's a business service then the operation is not the end goal but the means to the end.
If it's a business service then the question you should be asking is "should I care that my competitors are able to observe and monitor my service metrics?".
I'd file this under: things to not worry about.
