ForgeFlower is better than Spigots FernFlower at decompiling the source. However, in order to maintain the CraftBukkit patches, we must keep using spigots for the primary. However, for any file that we import on top of Spigots imported files there is nothing stopping us from using better decompiled files. So these changes will use ForgeFlower to maintain a better set of decomped files, so anything we add on top of Paper can start off in a better spot.
