I don't think it does.

The default Bluesky frontend uses bsky dot app URL when you use the "Copy link to post". Now if one day, you lose trust in this server and switch your PDS, this link continue working depends on this very non-trusted server. If this server is profit-seeking, it can break such links.

An extension or another app is not the solution, and neither is the new at:// URI format, because what matters is the relationship the default server sets up with its majority of users. Most bsky users will lose their traffic to their own posts and therefore will be locked-in, cementing this one server to be the dominant one in all perpetuity. We will therefore get all the patterns of monopolistic abuse that we have seen elsewhere.
