Nodes for working directly with RFA files?

Hello, I would like to develop some scripts that operate directly on RFA files.

I know the Orchid package has some useful nodes for interacting with parameters inside families but I have found these nodes to be unstable and leading to crashes. (I have another post about a specific issue, presently unresolved). Can anyone tell me if there are other packages out there containing nodes that I should be looking at? I’d like to the ability to read and write to parameters, modify formulas driving family parameters and create family types.

Thank you.
