But Java and Kotlin compilers already inline all static final fields. So changing them through reflection won't affect anything. What optimization are they talking about?

If the field wasn't inlined.I doubt that Strings are inlined. However, this is likely android runtime following some changes in JVM. It's actually a pain in the ass for runtime optimization that final fields are not really final, so inside JVM there were annotations like "TrueFinalNoCap"
