My turn for devil's advocate:
What you say is true. However, programmers and database modelers/architects
are two different skills. In large environments, the architect normalizes the
database first to 3NF, the denormalizes and adds indexes to enhance
performance for most common access paths.
Of course, this is what happens in large waterfall development shop, and
not in iterative development like most Open Source is.
Let us assume that is not an issue with Drupal, and that the core developers
are also efficient database architects (which is mostly true).
This leaves out contrib, which is very variable, and no database optimization
happens for the vast majority of modules.
I am not sure if anything can be done here to improve this though. There is
no silvert bullet for this one.
