I agree - really nice scan @nieda, and thanks for sharing your process.
I've not had much luck myself with shiny objects, although this brass door knocker came out well, perhaps as it had a lot of non-shiny context around it? https://skfb.ly/C6Bp
At the moment it seems that light based scanning would indeed require some re-texturing of a shiny surface - @3digify use an anti-glare spray for example: https://skfb.ly/EqoY - useful if the object is not precious or ancient but I'm not sure curators / collectors would allow such contact with their objects.
I've heard of "contact scanning" which uses a robotic arm to record points in 3D space too, but I guess you don't get a textured model at the end of it...
