"emulate sh" is POSIX shell emulation (we did amend this mode in the
past to work as much as possible as POSIX describes). Neither typeset
nor local are part of POSIX (at least not SUSv3 - I don't know about
v4).
So, I don't think it should be enabled.
FWIW, dash and posh behave like zsh's sh-mode here. Ksh93 doesn't work
at all, because it has no `local' (only typeset). Mksh, pdksh and bash
work like KSH_TYPESET was set in zsh.
