maxWorkerArgs handling was accidentally lost 3 years ago in a major update of demand analysis commit 0831a12e Old regression is noticeable as: - code bloat (requires stack reshuffling) - compilation slowdown (more code to optimise/generate) - and increased heap usage (DynFlags unboxing/reboxing?) On a simple compile benchmark this change causes heap allocation drop from 70G don to 67G (ghc perf build).
