Why would this be the case? Normal stack layout and register allocation already discards things that are not live across function calls. (With some potential wiggle room because that's not the primary goal, I suppose?)

I guess that the savings obtained by a more aggressive spilling optimizations are more appealing in case of long running async state. In any case real workload measurements should be the only judge.
