I'm not sure why we're surprised.
This entire gen has had spotty coverage of physical games at the best of times. Even on the biggest titles.
Just off the top of my head BG3 wasn't even available on disc, and Indiana Jones was only in some overpriced collector's edition.
I guess the odd way GTA6 is putting a code in a box is grabbing the headlines, rather than it just not being available on a disc.
