The sounds were loud and lasted several seconds. These were removed because most computing devices are now mobile. The sounds are extremely annoying and disruptive to hear from a stranger's laptop every few minutes during a meeting, a classroom lecture, wifi shop, cubicle environment, auditorium, airplane, etc... They could also be embarrassing to anyone who just revealed that they were not paying attention.

For a similar reason I used to set sound themes to 'none', and for screen sharing.

Though there was a story of one office that set everyone's sounds to classical instruments so things would sound like an orchestra tuning up.

Example of sounds that are very useful:

- device disconnected
