This portal is to open public enhancement requests against IBM Z Software products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

Imbricated tables are mandatory for json data
The issue is not in JSON PARSE/GENERATE statement but rather, it’s in COBOL Occurs Depending On data items (aka table).
COBOL tables are fixed in each dimension.
In addition, very subtle memory layout changes can occur if users are not keenly aware of the underlying memory representation.
This will result in bugs that are difficult to find and diagnose.
This would not be backwards compatible. Also, this is non-compliance to the COBOL Standard.
Hence, we do not think this is implementable and will be rejecting.
This RFE is still being discussed further.
