Yes, I was invisioning, for example, flying into a headwind, then making a turn such that now you are in a crosswind and your airplane now has some crab angle (since you aren't holding any rudder). This would not happen on a neutrally stable (directionally) airplane. If that crosswind then dissappeared, a stable airplane will then return to zero crab (again witout inouts from pilot)

another way to think of it is by applying a rudder singlet. an unstable airplane will spin as a result of a rudder singlet, while a stable vehicle will recover and resume with the pointy end forward. These cases are not steady state.
