asie [Why did you create your own mappings instead of utilizing MCP or Spigot's existing mappings?] fix formatting

 +===== Philosophy =====
 +==== Why did you create your own mappings instead of utilizing MCP or Spigot'​s existing mappings? ====
 +With regards to the Mod Coder Pack, MCP:
 +  * MCP's mappings have no clear licensing terms; between the old MCP license ([[https://​​Programs_and_editors/​Mod_Coder_Pack#​License_and_terms_of_use|as preserved on the Minecraft Gamepedia]]) and the new MCPConfig repository.
 +    * While other projects like OptiFine and Sponge utilize MCP, redistributing MCP mappings - which is forbidden without explicit permission - is necessary to support SRG-obfuscated mods, something [[https://​​MinecraftForge/​MinecraftForge/​blob/​1.14.x/​LICENSE.txt#​L32-L35|only done by Forge]].
 +    * Even if we had been granted permission, it is unlikely that we would be freely able to extend this permission to other developers. This would go against Fabric'​s core values of development freedom and transparency.
 +  * MCP's mappings are not always updated to every non-"​release"​ Minecraft version, nor are others generally allowed to do it themselves. This would forbid Fabric from updating to snapshots or other experimental releases.
 +    * Additionally,​ MCP's updating toolchain - as of the last few years - relies on proprietary Mojang information,​ not accessible to common users, as well as software without clear licensing terms. In contrast, Fabric'​s updating toolchain relies solely on free software tools (Stitch, Matcher, Tiny-Remapper,​ Enigma), and the artifacts of the process - just like the mappings - are publicly available.
 +  * MCP's mappings have an updating process we consider insufficiently open to code review, in our opinion, utilizing [[http://​​|IRC bot submissions]] over a merge request system. (However, this is largely a matter of preference.)
 +With regards to Spigot:
 +  * Spigot'​s mappings only cover the server side and are very incomplete,
 +  * Spigot'​s mappings suffer from similar licensing issues as MCP.
