The original ksh wasn't open source and might even have been an extra-cost item in AT&T unix. And the early emulations weren't always complete so you couldn't count on script portability. I generally thought it was safer to use perl for anything that took more than bourne shell syntax.
You're right about the extra cost. In 1989 I bought the ksh source code from AT&T for $100.
