Personally, I really dislike using this font on the wiki. If it were possible to execute properly, I would perhaps be more inclined to accept its usage, but it's literally impossible to get right in CSS.
Fonts will always land on subpixels, especially when you use rem/em/% values in a page. This leads to the font becoming blurry halfway through a sentence.
Additionally, you are limited to only being able to use font-sizes in multiples of 8 pixels. Anything else will also appear blurry.
Finally, it generally looks very out of place on the wiki surrounded by everything else. I don't think it's appropriate for anything except terminal renderers (which we don't have yet).
