It was removed because it isn't a feature I want to maintain or support long term and it was limited to a specific arbitrary file format and prone to errors if a user had data in a different format, ie it had no flexibility. That is also why it was hidden/disabled when it was built in.
The utlility file is inline code so it can be edited/modified easily with no need to compile it if needed to accomodate other file formats or data sources. Modification to meet different needs would not be possible if it remained a baked in feature compiled directly into mojoPortal.
Best,
