Token Gold is now rising whether there are plans on other exchanges such as Binance, Huobi, Kucoin.
I hope you are not expecting price pumps from these listings as gold token price will remain the same. But yeah, it will bring some awareness and liquidity.
In my opinion, team should not spend money on these exchanges since they charge hefty fees, their own instant exchange is good enough (also there are ethereum decentralized exchanges, where you can trade by using contract address).
I doubt usdt team went to exchanges for it's listing, exchanges themeselves felt the need to have stablecoin market and thus got listed, I hope the same for gold token.
Gold token supply and physical gold in bullion star wallet both can be audited anytime user want. I do not think there is any need for team to show up their faces as what is necessary, is given to us.
