In the end it depend on who’s on duty when you submit the name, as objectionable and undesirable is all subjective and depend on how closed minded or open minded the officer are. I know someone named Ranger(profession), Tiger(animal), and Hunter(profession).

Then we have Leon, which name is connected to Leo(Lion, animal), Rose Daisy Iris Marigold Lily is all flower(plant), Ruby and Jade is gemstone(object), Smith is profession. But all these has desirable connotation, so the “objectionable & undesirable” is basically mean the word that bear negative meaning or is demeaning, like babi or…idk, Corpseflower Tan or Portuguese Man-O-War Kamarudin.
