I think C++ devs have to eventually update their knowledge how Java and .NET work when talking about reflection.

Yes, originally they only supported runtime reflection.

Nowadays they have compile time tooling as well, via plugins, annotation processors, and code generators.

Which is exactly how you can have a Spring like frameworks that do all the AOP magic at compile time, for native code with GraalVM or OpenJ9, like Quarkus or Micronaut.
