That "improved SQL" was already defined in the previous century, and has been implemented as well. Your ignorance drips off of every word you write.

E.F. Codd literally designed null into the relational model. I don't think calling someone ignorant is very helpful.

But the demeaning ridicule that gets thrown at me is ?

(BTW I doubt very much that "Codd designed null into the RM". Even his 12 rules mention only "a systemic way to deal with missing information", not "null".)
