I reckon the 100-400mm doesn't offer sync IS because it's a Sigma lens - possibly featuring Sigma's miserable OS (not compatible to sync-IS ...) - which would explain the mediocre efficiency rating.

And while we are at ranting - why does this lens cost $1500 and the near-identical Sigma costs $800?
Sure there's the economy of scale - but it's also a way to push a system into oblivion.
