Is there any reason to use pancakeswap exchange and liquidity for trading?

Hi, Your exchange and liquidity are same with pancakeswap ones.
If you are going to create own finance, you need to create own Dex as well.
But you used pancake DEX.
In this file, you used pancakeswap sdk where factory address and init code hash are initialized.
https://github.com/goosedefi/goose-frontend-amm/blob/master/package.json
And router address is also same as pancakeswap.
export const ROUTER_ADDRESS = '0x05fF2B0DB69458A0750badebc4f9e13aDd608C7F'

could you possibly let me know the reason what you used pancake DEX?

Thanks.
