Bring Minecoins to servers on Java edition

TLDR: Allow Java servers to accept minecoins for ingame purchases of cosmetics/ranks with cash payout to server owners.

When minecoins were added to Bedrock, Mojang clearly didn't want to add them to Java Edition. Java has a large free modding scene, which would be a shame to shut down. A lot of the content created on Java Edition relies on the additions players can get from online or create themselves for free.

I think a good way for Mojang to add minecoins to Java is to add them as a currency for within servers. Currently, a lot of Minecraft servers sell ranks or cosmetics through online stores/websites. If Mojang were to add a currency to Java and allow Java servers to enable purchases with this currency, it would make purchasing products from servers much safer for the players as they wouldn’t have to trust these servers with payment or personal information. 

To sell digital products, servers currently must use online vendors, which take a percentage of each purchase (Tebex, the current most popular vendor, takes 5%). Servers must convince players to leave the platform to make a purchase online, often with limited payment methods. Making purchases within the server would increase server revenue for smaller servers and make it easier for players to support their favourite servers.

If this idea is implemented, it is important that server owners get paid in their currency and not in minecoins to motivate server owners to use this system instead of other vendors.
