I think so. There are always unexpected ways the jdk may break and third-party libraries would need a different workaround for a new java version. For instance, in Apache log4j, its library has a special guard against the broken implementation of Reflection getCallerClass during java 7. The libraries can just handle these in their version-specific components.

Especially given the fact that the code linked above already has version-specific handling (8 vs 9), so it won't hurt much for them to add another piece of logic to handle jdk 17+ in case this optimization is merged.
