Why no automatic sacrificial layers?

[esopalumpa 8]

A common method to print print holes with nothing below, without support, are sacrificial layers (2. fig.).
The sacrificial layer can optionally be supported (3. fig.).

Why is there no option to make Cura generate sacrificial layers automatically.
The rules are quite easy: horizontal overhang, not too wide, with holes in it.
