/bin/sh may be a minimal Bourne-compatible shell. Assuming that it is bash-compatible is a bad idea.
And: Is it really a problem to require bash? I mean there are scripts that require csh (yuk!)

I never used ksh, but AFAIR the only advantage of ksh was vi-compatible command-line edition (which bash can do at least as good).
Is there any good reason to require ksh for scripts?
