For example, I’m on Lemmy.sdf.org and I joined the [email protected] community. But there are many missing articles and comments. If I browse directly on Lemmy.ml for the same article there ~90% of comments are missing.

Yeah it’s still definitely an issue considering there will be plenty of old topics that people will want to search and refer back to, and any new instance or people making their own will be SOL if they come in years later after communities have been posting for a while.
