Hide empty fields in responses

[seime]

The response when converted to JSON contain field types that should or could be hidden.

• Empty strings, ie "version": ""
• XXX_UNSPECIFIED enum values (ordinal 0) , ie "status": "STATUS_ENUMERATION_UNSPECIFIED" when following the official style guide https://protobuf.dev/programming-guides/style/#enums
• Empty repeated fields/arrays, ie "validBetween": []

For some users I recon this is useful information, but for others this is just noise. Therefore I propose a config parameter to show/hide these empty fields.
