Should NS and wiiU be both labeled as 8th generation?

The Switch was released alongside PS4 Pro and Xbox One X so basically it's Nintendo's mid-gen refresh but unlike the latter two, it isn't sold nor share the library of the Wii U due to its lack of disc player. But it's still a mid-gen refresh

Dreamcast released alongside N64 and PS1 a full two years before the PS2 it's still considered the same gen as the latter.
