This would be extremely good. When working on Valhalla/Panama it 
happened to me quite frequently that, when changing something in the 
_implementation_ of one of the core classes (var handle, method handle, 
you name it), as a result, everything else needs to be recompiled.

After having witnessed some of the attempts with dependency tracking 
with sjavac, my personal feeling is that simpler is better - and what 
you have might well be a sweet spot in terms of complexity vs. benefits
