I'm sure someone would LOVE to pick it up and dump it onto BG, but we just don't know how to do it.
Plenty of people know how to do it. Windower (through ResourceExtractor) and Ashita both dump the item dat data. It's a matter of an hour or two to use existing knowledge to make a process that generates the correct output format including the images.
What we don't have is the backdrop used for their screenshots, the desired format specification, or the administrative privileges used for the import process. Right now, it looks like he runs a script on a local copy of the wiki files then does an import of all of them. I can see why they wouldn't want to give that access to randoms. However, it's been indicated during past updates that parts of the process are still manual for them, and at the very least they could accept help making it easier.
Trying to contribute items one at a time or do manual edits isn't likely to be helpful to their process. Using a bot to do it as normal edits is clunky and taxes the servers more plus could come off as condescending or rude. So, as long as they aren't interested in collaboration it's kind of stuck. I don't fault Funk for not dropping everything to update; it just seems like a more robust process could be established to remove the Funk-specific steps and a couple more trusted people could be given access to run it.
