About get_players, we agree, i told in my first post that the loop is acceptable (because of the frequency it gonna be called). I would use get_player though
About reliable msgs, i said that only in some situation i will kick players, and i coul'nt tell in which situations, so considering that the plugin only add some visual features that won't break the game if they are not sent, i really think it would be better to use non reliable msgs by default, that's not a must though.
Approval will depend on legitimity to release a plugin that has already 2 similar plugins and new features yours offers.
