Sort of. "Does not specify" does
not mean there is no connection between logical and physical layers. The relational model has strong implications for what a storage engine should do well.

agreed, the implication is that the engine should do everything well. rdbms is a product of being pulled in every direction, there's generally an index strategy for everything including fully connected hyper graphs, and that's how they ought to be because we can write wildly complex recursive sql queries and the goal is an efficient ideally optimal execution plan

I don't think you mean "everything, equally well".
But if you mean that database vendors feel pressure to have their "RDBMS" be able to "be competitive" across a wide variety of use cases and metrics, I tend to agree.
