I have not made up my mind about it.  The bash behavior when invoked
as `sh' (or in posix mode) is the historical sh behavior, and is what
other shells claiming posix compliance (ksh93, dash) or as close as
you can get to a straight-line descendant of the bourne shell (SVR2
sh, SVR3 sh, SVR4.2 sh) do.
