So many customers don't account for this and it up costing $$$ if your data model isn't a good fit. Cosmos even takes it further w. 1kb units (I have spent hours on Cosmos pricing and am still baffled on how to price a workload.) Although... it does incentivize decent data modeling practices which often lead to more performant apps.
