Overcommit should not be necessary in order to just reserve a range of VM without committing it. Windows gets this right (requiring explicit commit to use memory if you explicitly reserved it earlier). Demand paging on Linux is super-convenient (and my designs exploit it heavily), but you can’t really write robust programs that way.
