The Compatibility, Specification and Review (CSR) process ensures that all changes to exported interfaces are reviewed in depth to ensure they are well designed, and that compatibility concerns have been considered. These exported interfaces include the various flags and options that can be passed to the different command-line tools in the OpenJDK (java, javac, jlink, etc.)
For CSR purposes, only Hotspot's "product" and "manageable" flags are considered exported interfaces that require a CSR request when they are added, or commence the deprecation process.
For the other kinds of flagflags, a CSR request is not required, and it is up to the developer whether removal needs to follow (part of) the deprecation process.
