whole system look can provide some unexpected "optimizations" too. is balancing really even needed in/as a solution... in cases when synchronization is not necessary you can simplify system greatly just by oversaturating belts with inputs. output machinery cadence dictates whole feeding mechanism rate.
You can combine narrow balancers to make wider balancers. That way it is possible to save space, energy, latency .... same as is done in modern CPU / GPUs...
And funny enough, ultimate Factorio tool is tool to make great cpus... ;)
I like your, what i presume is, "joke" animation at the end…
