As far as powers/abilities go, something in filler arcs would only be left out if it completely breaks canonically established fact. If you look at, for example, the Kakushitsuijaku page, an episode from the Bount arc is used as reference to list Rangiku as a practitioner of the spell. Since there's nothing in canon that has proven that statement about Yamamoto wrong, there's no major issue with it. Games are a different story, as those are even more filler than filler arcs.
