Since RTCW (and maybe q3, I don’t know) and unfixed in ET, if you have too many .pk3 files (or perhaps, arena or campaign ?), and you try to host a game, the game will crash, or try to load the map multiple times or produce various other wierdness. If a dedicated server has too many files, the clients may experience multiple loads and other problems.
In ET, almost every user will hit this limit, because campaign files must be in .pk3s and are autodownloaded. This means, that, for your average joe user, after a short time of playing, they will no longer be able to host games Most likely, they will not figure out the problem on their own. Even un-installing and re-installing may not help, unless they know to manually delete the autodownloaded files.
How the developers can accept a bug that inevitably makes a significant portion of your product unusable to a large number of your uses is quite beyond me…
