-----------------------------------------

Thanks for the replies [~jrsteinebrey] and [~pvillard].

The {{FileParameterProvider}} works well with Kubernetes Secrets mounted as 
files, but aside from that specific use case, I'm not following the rationale 
for a properties-based implementation. Is there another container-based 
deployment strategy that would be expected to provide these values?

Loading sensitive values from an unencrypted local file does not provide the 
same security features of an external system, or the local flow flow 
configuration, as Joe mentioned.

The Variable Registry approach was removed for multiple reasons, so just 
attempting to provide a similar type of functionality does not really describe 
the intended use case scenario.

Base64 encoding aligns with mounted Kubernetes Secrets, but again, having a 
clearer connection to what process or service would provide these properties 
files would help clarify the implementation driver.
