It seems like the bake tool currently uses "Smart UV" unwrap for the objects UVs, but wouldn't "Lightmap Pack" be better? It covers the texture way better and since it is baking streching is not a problem.
Yes! I recall having some trouble with lightmap pack, it's currently commented out here:

Will sort that out.
Unwrap type can now be set in bake panel. (https://github.com/armory3d/armory/commit/23e17c7a2bce0e4aef4377bf6f3adace2a7a637e)
