It's a new addition, so I'm giving it time to see how it's going to be used in the wild and although I kinda like OP's take, the ones with giant images, GIFs, too much text... I'm not so sure. Maybe it's just like this now because it's a shiny new toy and people are pushing its boundaries but will die down later.

I'm lightly skewing towards just hiding it with a custom rule and forget about them. I visit a Github profile to quickly see what the developer codes instead of a showcase of their personality which, as you said, would be better served by a personal website.
