remove keepAutoPlacement (#544)

<!-- A new module or something else important -->
## Major features
-

<!-- A new parameter added to a module, or API feature -->
## Minor features
- use nullable values instead of separate keepAutoPlacement bool

<!-- Some improvement that requires no action on the part of add-on
creators i.e., improved star graphics -->
## Improvements
-

<!-- Be sure to reference the existing issue if it exists -->
## Bug fixes
