Why is there no support for BCF in ABD-CE?

There is ridiculously old thread concerning AECOsim and the Building Collaboration Format which is extremely useful in ArchiCAD, Revit or TEKLA driven projects. I assumed that Bentley did not care about that Format as it was requested for a somewhat aged version of AECOsim, iw. 32 Bit. Unfortunately the latest version of AECOsim still has nothing on the matter. I could not find any entries in the Microstation BASIC documentation on how to adjust cameras or open and close view windows when I tried to write something myself. But wait, now I would have to do that in VBA for which I do not have documentation at all. Perhaps importing BCF could even be incorporated into the 'saved views' dialogue. That at least does offer an import function. Maybe some online hints on how to access that dialogue from VBA can be found.

There may be some short answers to my question formed as 'Subject' along the lines of 'but our competitors don't offer support for BCF either', there are free and paid for plug-ins for other applications embracing BCF just none for ABDCE.
