It could be, but are vendors actually upgrading kernels along with firmware updates? In my experience it's more like, ship 5+ year old kernel and then forget it forever.

Certainly the big guys like IBM/RedHat are putting effort into maintaining their legacy trees.

I think that's the case with smaller vendors, like the teams that produce a custom kernel for the newest ARM single board kit. Once most of their inventory is sold they have little incentive to dedicate engineering bandwidth to updates. (And there's always the community effort to pick up the slack.)
