I suspect the Greek alphabet was given special treatment because of just how prominent Greek symbols are in math and science.

I posit that engineers and computer scientists gave extra time and attention towards accommodating Greek because they were so familiar with seeing and using those glyphs during their education. They knew that those symbols would be encountered in English, even before full internationalization efforts would take place. Whereas Turkish was merely an afterthought.
