I'd posit that it should not be bash then and somwone else might
reasonably want a different /bin/sh, perhaps even bash.  Which is
exactly why the alternatives system exists.

It's perfectly OK to use /bin/sh (I'd even recommend it) if all you want
is a POSIX shell.  You shouldn't be trying to use local then, but that's
another story (*).
