Oh, and as you basically go back towards my first fix that was reverted this

You'll need to be more specific. We are simply limiting the first SFT
of a nested struct out of the partitioner, instead of recursing into MPT
elements during operand scanning.
Where is the extra compile time coming from? Are we generating that
many more virtual operands? It would help quite a bit if you'd open a
PR with a testcase for me to reproduce this behaviour.
