I personally wouldn't use the feature. It may over-saturate the wiki when all that information can be contained on a character profile. I think this may just be reiterating another poster's point, though.
There's an issue I do wish to address and may be off-topic:
If RPers have problems of wiki-page bloating, I would suggest trimming down the larger sections of their character's profile page to the point where you feel the readers can understand the main idea you are trying to convey without going into needless detail. In general, many people tend to skim over prose or ignore it entirely unless they are heavily invested in the work. If the reader is interested, RPers can refer them to character journals, articles, and RP snippets, like an actual wiki would. These pieces can be on or off the wiki, depending on the preference of the page author.
