Missing methods and inconsistent calls on Fabric networking

[SrRapero720]

Example 1: CreativeNetwork#sendToClient(CreativePacket, Level, BlockPos); and its variants aren't available on Fabric version of CreativeCore

Example 2: Type registration is inconsistent, it calls methods like CreativePacket#executeServer directly instead of run CreativePacket properly On my implementation i made my custom methods for networking doing the common class casting and then calling my custom methods, making the default CC methods no-op throwing an exception

Again, working on forge, not on fabric, because type register adds the consumer calling sided execute methods directly
