Attitude to the legend Kamili Davidovicha

In one of the responses to the recent columns, it was stated on behalf of the Chass (without source) that the legends of the Chass were written as "Mili Davidihota", and not as a binding Torah part.
Since I also remembered something like this, and out of gratitude to the rabbi and the website, and due to the opening of the online treasure trove of wisdom to every bounded and absolute, I searched and even found what my soul loved, and I copied it here.
Rabbi Yedaya the Penini Bardashi (who is cited in the Rashba's Responsa and is known as the Avonite Sage), believes that there are many legends that have no meaning, and their function is only to introduce words of wisdom and prosperity into the study, and this is his language:
The third part, all the articles that tell of no innovation that departs from the custom, and on the general principle that this change is of a nature that we will not draw from it any benefit explained in faith or any strengthening, but rather that it will be mentioned on the side of the story alone, for the benefit of the students and the need to introduce them to the words of David, to put aside the dignity of the study and the labor of the version, and this is in the stories of Rabba bar bar Hana and their inferiority complex from many similar ones. Here we will certainly interpret this language and take it out of its context, even though it is undoubtedly possible by the law of God's power, and without drawing from it any benefit explained in faith.
(Cited in the Rashba's response, section 18)
And so the Rashbatz wrote in his commentary on Tractate Avot, and he goes on to praise the legends that are for the purpose of expanding his heart, and this is his language:
And when his body finds itself weak from studying and he has to walk a little in the markets and streets, he will do this in order to broaden his heart to return to his Talmud, and as the sages said (Shabbat, page 30), because the rabbis were weak from their studies, they would say words of mockery (- when the sages were tired from their studies, they would say things that were funny), and this is the matter of the foreign legends found in the Talmud. (Magen Avot on Tractate Avot, Chapter 2, Mishnah 17):
