Well, maybe, but supporting such a switching script means all
scripts starting with
#!/bin/ksh must remain portable between ksh88 and ksh93.
And scripts which want to use new ksh93 features will
need to start with #!/bin/ksh93. I suppose that will happen
anyway after /usr/bin/ksh93 gets integrated, but I don't necessarily
want to reinforce that behavior after ksh93 migrates to /usr/bin/ksh.
Ultimately, I think we want to try to obsolete ksh88, and
a switching script could end up being a crutch that prohibits the
full migration to ksh93.
