Description

Currently, Propeller seems to perform optimally when there are no changes to the source code between the training and application stages.
In a production environment, it can be challenging to seamlessly transition from training to applying the profile model.
Additionally, users often prefer to retain the generated profile for an extended period, expecting it to degrade gracefully over time, and then refresh the profile when the degradation becomes significant.

Is there any plan to implement a feature in Propeller that would allow for the prolonged use of a generated profile, ensuring it remains effective over a longer duration?
