In this case the benefit would be:

- your data lives in one place, your Personal Data Server (PDS). You can self-host this if you like - The AppView (in this case, tangled.org) aggregates the data from many PDS's into one view. - If tangled.org enshittifies, you can do all the same things from any other AppView -- tangled.org itself is not privileged in any way.

Social logins on independent forges help, but personally I'd rather have a single account to manage -- and the AT protocol means that any individual forge can go down, but the data remains accessible from other AppViews.

In this case the PDS is only storing social data though, right? The forge would still store the repository data itself.
