Yes, I would be surprised.
Because, unlike most products which only require training to work with, true RDBMSs require knowledge of data and relational fundamentals and such is scarce today, because education has been replaced by sheer training.
How many database "experts" do you know today who have any background in logic and math, particularly those designing DBMSs?
I've watched them for almost 50 years and they've become worse and worse, not better.
