No doubt, if there is an alternative we can push for it to be
implemented. I guess this being yet another "IPU" there could
be possible workarounds in FW? As always with IPUs - hard to tell :/

If there is no alternative - it is what it is. 
It's up to customers to buy good HW.

That said, looking at what this set does - how are the VFs configured?
That's the showstopper for the series in my mind.
