See my above comment. I don't care how many different apps use it... why should that matter? Enough serious applications rely on it to ensure it's not overtly buggy and doesn't contain lots of silly security holes and that's all that's important. Having it part of LSB ensures it will be there, and it will be supported, and it will be backward compatible. That's absolutely critical for those who don't want to be forced to recompile their software for every given distro and distro version.
