You can make precisely the same argument for network services. Who knows, maybe you need telnet and UUCP and NFS and ftpd running on your system?... why should the distro maintainer decide?

Well, because you probably don't, and it's a security risk, so no need to put millions at risk for the benefit of that one person who wants to tinker with packet radio or whatever. Similarly, it would be prudent for distros to not allow autoloading of modules that are extremely niche while giving a simple way to adjust the settings if you want to. God knows they have plenty of GUI configurators and config files already.
