This is likely my fault - as David notes, accidental and during some re-factoring. The problem is, as he mentioned in his original email, there's no straightforward fix: reset clearly should reset controls (magnetos, flaps, stick input) to a default state. The definition of 'default' being the issue. 'preset-commit' should possibly not trigger a full-reset - but I'd worry about introducing subtle bugs in re-position from the GUI, if we change that behaviour now. On the other hand it is fairly testable, if breakage does occur. My 'least bad' option is to save control state (from the -set.xml, or config, or command line) as part of the initial state, so that it's re-applied after the controls are reset. That seems to most robust to me, but I need to check if there's knock on effects (possibly rather subtle ones) from saving and then restoring more properties during the reset process. Other suggestions most welcome!
