It's not because the M3 MBA appears in developer logs that it means it will launch soon. Look at this article from April 2022 citing all the M2 Macs being tested, the source being developer logs. The M2 MBA was launched 2 months after this article, but for the Mac Pro, it was more than 14 months after this article.
Now, I can see Apple releasing an updated M3 MBA in spring 2024, or even maybe in early 2024. But I don't believe in the slightest that an updated MBA will launch this fall.
So not only this doesn't prove anything, I think you are misleading people by citing the 9to5Mac report. This report clearly states an M3 Mac mini as a possible October launch, not the MBA.
