It's odd imo

That's exactly it. If a child is born to a Jinjuuriki, they have whiskers. We at least know this to be true about Kurama host's children. Think of it like Kurama & Naruto/Kushina having their DNA or life forces mixed together into one being, that's pretty much what it is to have a Tailed Beast sealed within. That's also why the host dies when the beast is removed (with the exception of some Uzumaki Clan members because of their huge chakra resevoirs, Kushina probably would've lived if Kurama hadn't stabbed her) and the beast also dies before being reborn. They sort of depend on each other to keep their life forces going. Kurama gave Naruto & Kushina his chakra many times to protect them from dying in battle, so he also wouldn't die. None of the other Tailed Beasts' Jinjuuriki have whiskers because they weren't born to a Jinjuuriki, they were just chosen to be one.
