ODB++ PCB CAD Data

I am having an old board made and am being asked for ODB++ format CAD data files.  It seems this is to facilitate the creation of the various machine control files.  I'm told it can also support locating traces to assist in debugging.  My CAD package doesn't support this.  Would it be a hard thing for the developers to add?

Doing a little digging I see it is a proprietary format promoted as open and seems to be most commonly used while there are alternative formats which do the same job.  Seems Gerber has been updated to X2 by adding attributes which can identify the file purpose, pad functions, etc.  Add netlist information using IPC-D-356A and the data set is complete.

Then there is IPC-2581.  Decades ago IPC created an end to end format to convey all board design info.  I don't recall the nomenclature, but they never got support (I think mostly because the industry is very parochial and doesn't look very far ahead) resulting in the standard(s) being dropped.  I don't know if IPC-2581 is a consolidation of that effort or a new effort, but it is gaining ground. 

I don't know which format is better or if more than one should be supported.  I've been asked by two companies for ODB++ format.  One asked for it to debug boards after fabrication and the other wants it to support setting up their assembly machines.  I didn't know about the other formats at the time so I didn't ask.

The problem with the ODB++ format is that there isn't any decent free
software to open it (as far as I know).

My preferred solution is to use the CAM350 format, which is a Downstream
Technology proprietary format but it can be opened with their free viewer:

It supports most of the ODB++ features (net/component highlighting, etc).
In fact most of the PCB layout designers I've dealt with can export either
in CAM350 and ODB++.
