In these instructions for working through the plutus pioneer program, it suggests installing the playground locally: https://tutorials.cardanoacademy.io/plutus-pioneer-program/setting-up-plutus-playground/starting-plutus-playground
However, the end result is to then just use the same web gui but on your localhost instead of running it on: https://playground.plutus.iohkdev.io/
So, are those docs just outdated or is there some advantage to running it locally?
Thanks!
