Chiming in to support this. DriveThruRPG already had this for a long time, but when DMsGuild and other Community Creator programs on their site launched, they didn't start with that feature. Once they did implement it, however, DMsGuild in particular went from being "that neat place where people post their homebrew stuff in Word Docs" to "Announcing the Guild Adept program!" and record-breaking sales on collaborative projects like Uncaged and many others.
Coordinating royalty payments with folks in the US, UK, South American and New Zealand isn't exactly easy or fun, so having that sort of tool will certainly boost the profile of itch among smaller publishing teams like these, who still put out amazing, quality work that sells on the order of tens of thousands of units in some cases.
