Research direction
Start with the linked Spring Boot issue comment, then inspect IndexElementBinder and SystemEnvironmentPropertyMapper to understand the removed optimization and the legacy mapping it must support. Trace the current filtering path and compare it with the legacy behavior; the work is done when that mapping is supported without regressing the existing binder behavior.
