May I ask what is the reason for using fabric over something like paper? Is it because you want it to be as vanilla as possible?

Yes

@ProGamingDK Purpur has options to restore vanilla functionality, right?

Im not 100% sure but some of the modifications bug/exploit fixes, e.g. dupes How much ram does your system have?
