Why do you believe this?
ksh88 vs ksh93 deltas are described as features or improvements by the
ksh93 maintainer.
ksh88 vs pdksh deltas are described as bugs by the pdksh maintainer.
Why do you believe that pdksh makes less problems than ksh93?
The potential reaction of the maintainer to bug reports and patches like
"this fixes the XXX incompatibility that your ksh has with ksh88"
will differ. With ksh93, the response will tend to be "we don't care",
while with pdksh, it will tend to be "thanks".
Unless we are willing to fork ksh93, this hurdle may well be much greater
than all the technical issues combined. Of course, If we are willing to fork,
the cost of forking and tracking needs to be included in the comparison...
