Not everything is about RU usage, this is simply bad dev experience. It's not super straightforward, when you decide you need to order by a certain field, to process all existing documents in the database so that they have the required lower-cased property. We have the ability to do that in our project thanks to our custom schema versioning solution, but without it it's not an easy task in a big database, and it's a lot easier for devs to give up on "nice to have" features.
I suspect it's difficult to implement, considering the number of optimizations in place in Azure Cosmos DB, but please revisit this soon.
