You (perhaps intentionally) ignore the power of marketing.  Do you *REALLY*
think people need 192 kHz sampling?  no, but people are spending money on it
because the marketing tells them to.  Sooner or later, some host company
will claim full 64 bit data paths, and poof, GMPI is suddenly "legacy".

I'm really fine with whatever, because I am sure that sooner or later we
WILL end up with float32 and float64 in the same graph, and we'll have to
support it.  Whether we do it now or later, I don't care so much.
