I don't think wavelight and shoes matter so much in the 800m. (They were probably the game changers behind Cheptegei's und Gidey's 2020 WRs, though.)
I also agree that Mu will probably run as fast as Wilson did within a few years (sub 1:56) and it would rate higher because she would have to do it without being dragged by Semenya running even faster. But 1:53.28 is quite some distance from 1:55.5. Of the 27 runners below 1:56, Wilson is the least suspicious (and recall that tainted beef), and of these 26 only three (incl. Semenya) got within a full second of the WR.
It's great that the women's 800m that appeared pretty lame in the first post-Semenya season got better again last year and will continue to do so, but people should not underestimate how rare sub 1:57 are, especially if one excludes Eastern bloc 1970s/80s and a few Monaco races "paced" by Semenya a few years ago. So Mu could clearly dominate the next 5 years with several ~1:55 marks but still be a safe distance from the WR. It also remains to be seen how well she fares running rounds and more tactical races.
