I see your point if someone is at the level of tinkering enough to learn Mikrotik gear. I was loosely equating VRF with general Linux policy routing, where you end up owning a bit more of an overarching config with fwmarks etc. And then I reasoned that Mikrotik was more complex than that, because I personally avoid doing config on my Mikrotik devices in favor of the Linux router (which is the opposite if you're coming at it unopinionated). But if someone wants to understand just enough networking to copy and paste Mikrotik examples, I do think your post is good general suggestion for that.
