It’s not about ‘hiding’ but more not their business… or not player-friendly…
For example, some database resources or local backup resources, which does not use client-side scripts, and do not really affect gameplay (understatement), but I just wonder why it is publicly informing everyone what is the name of the resource, which not representing anything as they don’t even download it.
Obviously, as a player, I’m really into transparency and the right to know what a server does to my PC when I connect to it. But hiding was not what I was thinking about.
