> I now have to satisfy some absurd ideas about how functional async meta higher effect bullshit should work. All I need is to process events and update MY model (not some convoluted async representation of it smeared across visual elements and their lifetimes), from which something would update control values and text blocks
Could you elaborate on this? I'm not sure what an "async meta higher effect" is.
Reading in between the lines though, I suspect you're talking about state management. You might benefit from one of many state management solutions out there - redux, mobx, legend-state etc. Keeping and passing around local state spread out across lots of components can get unwieldy pretty quickly.
