Long term goals include subcircuit-in-subcircuit, maybe supporting 
hierarhical netlist too, and when these happen, your use case will become 
a trivial addition on top of the strong infrasucture.

However, please note that even small parts of this infrastructural 
change is very expensive and will take long. I'd be happy if we got only 
the first 3 stages I listed in the original mail finished in the next 2 
development cycles. And that means we "only" replaced the old footprint 
model with subcircuits.

How fast we get to solve your example use case also depends on how fast we 
get the basics (subcircuits as footprint replacement) stable. So please 
stay tuned and test the new code as it's being implemented.

Best regards,

Igor2
