The safe bet is to treat this place as temporary. I've enjoyed searching for a relatively simple solution for having a personal activitypub instance but I'm not sure the search is finished. FOSS is amazing and should be explored when considering software options IMHO. I was inspired to use this domain for my social posts partly because I think that ActivityPub is important and should be encouraged as a truly decentralized federated example. The other part is the handle verification system on Bluesky. I'd like to be able to mirror, or crosspost between the two protocols at some point via my own means. It's practice and I'm not finished learning.
