Would a stream enterer no longer need the "I am the owner and heir of my karma" reflection? The following sutta quote shows the reflection that would cause the diminishing or abandonment of misconduct.
However, this appears to be a method of skillful means for reflection by someone with self-view.
A stream enterer would have discarded self-view (sakkāya-diṭṭhi), which is the first of the ten fetters.
Therefore, would a stream enterer also automatically abandon the following skillful reflection or perhaps not need it anymore?
From AN 5.57:

“And for the sake of what benefit should a woman or a man, a
householder or one gone forth, often reflect thus: ‘I am the owner of
my kamma, the heir of my kamma; I have kamma as my origin, kamma as my
relative, kamma as my resort; I will be the heir of whatever kamma,
good or bad, that I do’? People engage in misconduct by body, speech,
and mind. But when one often reflects upon this theme, such misconduct
is either completely abandoned or diminished. It is for the sake of
this benefit that a woman or a man, a householder or one gone forth,
should often reflect thus: ‘I am the owner of my kamma, the heir of my
kamma; I have kamma as my origin, kamma as my relative, kamma as my
resort; I will be the heir of whatever kamma, good or bad, that I do.’
&quot;the monk, when not loaded down, does not load himself down with pain, nor does he reject pleasure that accords with the Dhamma, although he is not infatuated with that pleasure. He discerns that 'When I exert a fabrication against this cause of dukkha, then from the fabrication of exertion there is dispassion. When I look on with equanimity at that cause of dukkha, then from the development of equanimity there is dispassion.' So he exerts a fabrication against the cause of dukkha where there comes dispassion from the fabrication of exertion, and develops equanimity with regard to the cause of dukkha where there comes dispassion from the development of equanimity. Thus the dukkha coming from the cause of dukkha for which there is dispassion through the fabrication of exertion is exhausted &amp; the dukkha resulting from the cause of dukkha for which there is dispassion through the development of equanimity is exhausted. - MN 101

&quot;I am the owner and heir to my karma&quot; is a fabrication against heedlessness as a cause of dukkha. Other skillful reflections in AN 5.57 are fabrications against other causes of dukkha.

So he exerts himself with stress &amp; pain, and while he is exerting himself with stress &amp; pain, unskillful qualities decline in him, &amp; skillful qualities increase. Then at a later time he would no longer exert himself with stress &amp; pain. Why is that? Because he has attained the goal for which he was exerting himself with stress &amp; pain. That is why, at a later time, he would no longer exert himself with stress &amp; pain. - MN 101

Once the goal of a fabrication is achieved, there is no need to exert and load oneself with the pain of the fabrication.

&quot;Now when a monk... attending to another theme... scrutinizing the drawbacks of those thoughts... paying no mind and paying no attention to those thoughts... attending to the relaxing of thought-fabrication with regard to those thoughts... beating down, constraining and crushing his mind with his awareness... steadies his mind right within, settles it, unifies it and concentrates it: He is then called a monk with mastery over the ways of thought sequences. He thinks whatever thought he wants to, and doesn't think whatever thought he doesn't. He has severed craving, thrown off the fetters, and — through the right penetration of conceit — has made an end of suffering and stress.&quot; - MN 20
