Why do you think the same "half press prefocus" does not work for DSLR
users? And why they can't use smaller apertures if they want more latitude
to focusing error?
The ability of most DSLR's to produce far better pictures at far higher ISO
means you can easily use smaller apertures if you want the same depth of
field as those POS cameras.
Not having the ability to throw backgrounds out of focus is often what makes
those toy camera portraits less than satisfying though.
