">You can try this yourself with complex queries and simulating some load."

I do not need to try it. I know what it takes to parse/validate this kind of queries and then manage to get and assemble the results from numerous sources.

>"But it‘s an issue that can be solved."

No. This issue will not be solved as in general it is a problem of mapping one storage / functionality format to end client format. It can be easily solved for particular situations by writing custom servers (this is for example one of the things I do) but doing it generically introduces overhead / costs that are very unhealthy for a normal businesses.

And it is of course bad as it wastes energy.
