I have a friend who I help a lot with scripting and he helps me a lot with building, currently whenever he needs my help he had to copy his script, paste it into Skype and send it to me, I then copy it into studio and send it back to test, if there is an error then he has to copy it into Skype, I have to paste it into studio, etc etc.
As you stated in your post about friend request restrictions, arguments against an idea do not help.
Please do not go against an idea just because you personally will not find it useful.
