Boolean face FeatureScript

A very common thing I do with FeatureScript is use a tool solid body to cut a hole in the face of a surface or solid body. However, the two robust methods I can think of are awkward.
1) Use opSplitFace to cut the face, qSplitBy to find the new faces, evCollision to find which faces intersect the tool body, and opDeleteFace to remove them.
2) Use opExtractSurface to copy faces of interest to a new surface body, opBoolean to make the cuts, opDeleteFace to delete the original faces, and opBoolean to merge everything back together.
Both are quite awkward (am I missing something?), and the second option breaks the parametric history since the faces are copied and stitched back to the body. I could wrap this in my own script, but it seems Onshape should support this natively by allowing faces as the target of opBoolean instead of just solid and surface bodies.

I want to cut a hole through one face without going through the second face; for many designs with thin walls and organic geometry, it isn't feasible to reshape the tool body to avoid cutting the second wall. Also, Boolean's can't delete faces if the target is a solid.
It isn't a big deal since I have workarounds, but I was surprised there doesn't seem to be a simple way to do this by default.
