* whose major.minor version is less than the major.minor version of this metadata ([metadataVersion]).
* * 4 - this class file is compiled with the new Kotlin compiler backend (JVM IR) introduced in Kotlin 1.4.
* * 5 - this class file has stable metadata and ABI. This is used only for class files compiled with JVM IR (see flag #4) or FIR (#6),
* and prevents metadata incompatibility diagnostics from being reported where the class is used.
* * 6 - this class file is compiled with the new Kotlin compiler frontend (FIR).
* * 7 - this class is used in the scope of an inline function and implicitly part of the public ABI. Only valid from
* metadata version 1.6.0.
