I don't agree with this at all to be honest. The only thing people want nowdays is having everything binded but it only takes less than 2 second to write /res and the ID. I know it could be good to people who want's to answer while driving.
EDIT:
I'm confused, you mean to replace the atual system or just add that option on it?
Nvm, underestood it wrong. I thought you wanted to remove the ID option on it. As I said above, to people who's driving and want to answer fast to a call it could be good to have it. You just need to edit the current script, won't make any diference at all.
