Yes, but I'm guessing they will open up the currency so that 3rd party servers can use it rather than having to deal with payments on their own.
Hopefully it will help legitimize a lot of the current server networks.
While that would be great, I don't think it's going to happen. It smells like this is a feature limited to the relatively closed ecosystem of the non-Java version of Minecraft. Is it even possible to create heavily modded servers with the non-Java version. I'd be surprised, but maybe things changed in the recent year. If not, this doesn't help the existing server networks at all.
Do you think it will be an option?
Dealing with payments may be hard, but being a "sharecropper" is terribly risky.
