The idea behind this is not to allow them to launch a beacon asap - but to give them a heads up that transactions are working. It's supposed to be a test transaction.

Regular faucet transactions can take a while, donations as well. Buying GRC just to see if the wallet is working is a process that can take days if someone does not own any crypto coin and needs to set up new accounts for fiat exchange and BTC/GRC exchange.

While faucets, donatations and GRC purchase can be considered "wallet test runs" they just take too much time for a simple verification process imho.
