Offset Path, Outline Stroke, the Pathfinder panel, Clean Up, Make
Blend, Rasterize and the other commands that #1429's table marks 3,
except Split Into Grid, added, removed or replaced their objects one at
a time, and so did Remove Anchor Points, Redefine Symbol and the
removal of Shaper groups whose source art is gone. Each insertion or
removal moved the later objects of the layer or group. The lookups by
id that followed walked the tree, and every fourth walk rebuilt the
lookup cache. On 25,000 rectangles a release build of vectorcraft-cli
took 29.1 s for Offset Path.
These commands now make their edits with Document::wrap,
Document::insert_beside and Document::remove_many, in one pass over the
children of each layer or group, and Outline Stroke and Expand write
each new object into the place of the object it replaces. A list that
holds an object twice, or an object and another inside it, and that was
edited without an error before, is still edited one object at a time.
The documents, selections and undo steps are the same. On the same
rectangles Offset Path now takes 1.3 s.

The issue asked for one-step symmetric shapes, splitting all selected art
along a line and cropping art to a rectangle as real geometry. Only the
freehand Knife and the Scissors existed, and neither works on compound
paths as one shape.
New commands path.mirrorCut, path.lineCut and path.rectCut cut the
selected paths and compound paths (inside groups too) with pathops
booleans against a half-plane or rectangle, and split open paths with
the Knife/Path Eraser helpers. Mirror & Cut reflects the kept half and
unites it with itself (open halves are joined on the axis). The draw2
piece helpers now rebuild compound paths too. Three tools (Eraser group,
original icons) preview the cut live while dragging and commit it as one
undo step; Mirror & Cut's axis and kept side are tool options shown in
the Control bar.
