??? Of course it is required.

There were some attempts to use higher speed but it was not generally  
accepted.

Maybe, but in the end you have to go down to MIDI speed, if you want  
to talk with common MIDI instruments.

But many modern instruments started to use USB for MIDI transfer.  
Yamaha has their modification of FireWire protocol called m-Lan for  
audio and MIDI communication.

Yes, lot of changes, useful additions and improvements. Despite basic  
limited features it's still usable when used cleverly.

Sorry, but I don't see any connection between audio and MIDI. Two  
totally different attitudes...
