I can see it being useful for exactly that sort of thing. I've approximated hexagonal grids in spreadsheets by making each cell a square and then merging adjacent squares, alternating by row:

  [  ][  ][  ][  ][  ][
   ][  ][  ][  ][  ][  ]
  [  ][  ][  ][  ][  ][
   ][  ][  ][  ][  ][  ]
  [  ][  ][  ][  ][  ][

Useful for working on puzzles like https://puzzles.mit.edu/2021/puzzle/triangles/
