There are some Pros and Cons in this Suggestion which I would like to point out clearly so that it will not look so complicated
Pros:1. Can be transferred fast with a command (depends on how long admin takes to approve it)
2. No need to write such format in the forum
3. No need to register multiple accounts everytime you need a new nick
Cons:1. Can be rapidly spammed if someone intentionally wants to bother admin+ (unless if developer can give a timer to it)
2. Forum activity will be decreased
3. Someone can req through someone's account if he can manage to hack it
4. Takes alot of time for the developers to implement the command and the function to it (which takes alot of time than for a player to make an application on the forum) in the same time they could do something better than a single command and they are not as free as the regular players.
5. May creates alot of records in the database of the server which only a Dev can access and they will have to save it forever. (Tho I don't have much experience in this but I guess it records in the database if it's inplemented in the server)
Therefore it is upto developers whether to implement it or not. Thank you
