Currently, if you want to develop or test Aragon in an environment other than Ethereum Mainnet or Rinkeby there is a large barrier to entry. From a development perspective, this can be problematic and create friction that reduce the ability for other Dapp and Protocol developers to integrate Aragon.
1Hive has personally experienced this challenge developing Apiary, as the local ganache environment is not suitable. Additionally conversations with other projects about integrating Aragon have been hampered by the lack of availability of Aragon on other test networks. Goerli in particular seems to be a popular choice for developers, and it would be great to ensure that anyone developing regardless of what testnet they are using has the power of Aragon at their fingertips.
