So it only works if it is pretty much standard on mosts devices.
2 - Many people only know how to use the default apps on a device. 3 - For phones etc - it may not be possible to install different software 4 - Often what you can use is determined by your company. You get what they give you or offer and cannot use alternate devices or software. For these and similar reasons - it is important that such capabilities be supported. Users can turn them on or not but they need to be able to.
