The bug

The gamerule logAdminCommands only logs the feedback of commands but not the actual command, this makes the gamerule partially useless since often command feedback is not really meaningful or for some commands like /tellraw there is no feedback at all.

Note: Possibly a way has to be provided for commands to censor arguments in case some modded server uses passwords (or similar) as command parameters.

How to reproduce

1. Set the gamerule logAdminCommands to true

   /gamerule logAdminCommands true
   

2. Use the tellraw command

   /tellraw @a "Some message"
   

   → The command used is not logged
