Why not today?
I present to you 'LatticeMeshMirror(LMM)' Aka 'Lattice Mirror at home'
https://files.catbox.moe/wh4m8p.py
Features:
>1. Create Quick Lattice
Auto set-up a Lattice on a symmetric mesh centered on the world axis.
Cons: Editing the resolution of the lattice in the 'Object data properties' breaks the auto scale.
>2. Mesh deform method
Uses a mesh replica of the lattice and a MeshDeform modifier to control the lattice.
Allows mirroring in 3 axis and all the features of mesh edit mode with the smoothness of a lattice.
Cons: Only fully affects the outer boundary points of the lattice.
>3. Armature method
Parents a bone to every point of the lattice using bone envelope influence, allows you to reset the position of the points and animate the lattice.
Cons: Only mirrors the X axis and no Proportional editing.
>4. Mirror Mesh method
Cuts the mesh in half and adds a lattice to half of the mesh. Allows cutting in 3 axis.
Cons: The centerline of the mesh will break if the center points are moved away. BSpline mode is not recommended, other modes work fine.
>5. Apply lattice
Quickly applies and deletes the lattice
