The only basis for Gen not being canon is that in Capcom's finacial reports (https://twitter.com/dubindoh/status/896429917990080512), it's classified as a "spin-off" (just like Portable, G, Portable 2nd G, Portable 3rd, Tri G, and 4G prior, and a step above Iceborne, which is DLC). Unless we're suppose to assume that all of the games and expansions listed above aren't canon, there's really no reason to assume that Gen/GU isn't.
