For those interested in an update on this, the work is currently parked.
What could spring it back into life is an enhancement to the Jade product where a new type of file format is provided which does the job that scm and ddb files currently do. The ideal would be a readable/editable format which allowed for easy compares & merge of code and that largely ignored environmental info.
As per the demo it’s possible to roll our own format, but I’d just be concerned with the maintenance overhead and undocumented edge cases that may leave it unfit for commercial use.
