 However, if you are making a significant change to the way Vortex functions, you may need to write an RFC first. Some example changes that would require an RFC:
 
-* Making a risky change to the format, such as adding new required fields to file metadata
-* Rearchitecting core components of Vortex, or wide-ranging refactors that might break language bindings
-* Creating new libraries or SDKs that we expect others to adopt
-* Making changes to subsystems that are likely to affect performance if not done thoughfully, such as the core IO traits
