Earlier quoted context omitted.
While there are formatting guidelines, I've never seen them so specific that you could only easily do it in Latex. Is that really common? I've never actually see it as the assumed default option.. Maybe a decade back I could see that.. but not now.
The matter isn't really that something is possible only in latex, but that a department/university might have its own template/document class of arbitrary complexity that you would have to reimplement
I think there is a limit to how complex they can be. If you can't do it relatively easily in Word, then it's probably going to create too many complaints for the bureaucrats
