> What was straight spelling 10-20 centuries ago is now mismatch
I'm afraid you don't know how things work when people are used to phonetic correspondence: pronunciation changes, and spelling follows naturally.
As an example, consider the name of Florence. Originally it was "Florentia", today it is "Firenze": the name itself changed, and the spelling followed suit. That's because people in Italy do not ever ask themselves: "How do I write this?". The alphabet is there to express how you pronounce it, and not to support a parallel written language that does (not) evolve by itself!
Spelling bees are for those poor souls who saw their language drastically changed when being invaded by the kings of silent letters and wasted ink.
