Ah okay. To me "tree shaking" was implicitly talking about the dependency tree and removing unused library dependencies. While "dead code elimination" would be a "deep" clean done by a linker when making a static binary (mostly C/C++ land..). There you're looking at a finer granularity than libraries/compilation-units. That's necessarily a bit trickier and I wasn't even thinking that far. But it seems the GraalVM compiler work on this level.
