Yeah they should definitely have their pages.

I personally don't consider it as canon until I see some of it in the story. If Togashi actually mentions and expands on the new things Ishida introduced then maybe we could consider it as canon, for now he's just saying it, he might want to redraw the Ishida oneshot though, I find it a little weird that Hisoka's canon backstory would be some rough sketches on a web page done by another mangaka, it doesn't have the allure of an official (canon) material.
