Actually it doesn’t work that way in life.
  
1 - If you want to call someone - you don't get to pick the technology that 
they have.  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.
