Testnet/devnet tokens

Hello,

Creating an ESDT token on https://devnet-wallet.elrond.com/ is quite easy.
If I want to test the usage of this token on maiar.exchange, do I have to go through all the trouble of creating a PR and filling the data?
Why can't we have unbranded tokens on test environments?
Is there a special PR process for dev/test token branding?

Thanks in advance.
