Guess you're finally in luck.

Rubén created and maintained Boost for Reddit as a single dev as far as I know, and I would assume he's doing the same for Lemmy. I don't think he was ever frequently communicating on Reddit either, only now and then. Plus, he wasn't going to create a Lemmy version of Boost initially, so it really hasn't been in development long.

You just have to be a little patient.
