Look at the development of drum machines and sequencing hardware and software over the last several decades: you see even in those explicitly synthetic contexts attempts (increasingly successful over time) to incorporate "humanizing" dequantization / groove concepts into the generation process, as an attempt to capture when desired that very tendency of organic drummers to display some micro tempo dynamics from stick to stick (or piano chording to piano chording-certainly the concept applies to more than just percussion, though that's the obvious touchpoint).
