Why do walls need a walkable perimiter that isn't diagonal?

See subject.

Dwarves will build diagonally but they require that a nondiagonal perimeter be present first.

Wouldn't it be better to do away with the nondiagonal perimeter?

Technically the walkable perimeter is to insure that the wall is supported, and support does not exist on diagonals, all of that may change as Toady continues to refine the engine.  For now and the forseeable future though, it's probably staying.

Walls can't be supported diagonally - you can designate them to be built, but they won't actually be built unless they have an orthogonal support. If you remove all orthogonal supports from around a wall (including supports directly above and below), it will collapse.

There was a typo in the siegers' campfire code. When the fires went out, so did the game.

Yes... but walls that already have orthogonal support (including above/below) should be able to be built diagonally.  This mostly is a problem for me when walling off mining tunnels.  I breach the caverns or probe into the magma sea looking for candy, and then can't build a diagonal wall next to the stairs.  All supports (or maybe just missing one out of 6) supports are there! Natural stone layers even.  *sigh*
