acl:trustedApp limits usefulness of decentralized social apps

As was already pointed out in https://github.com/nodeSolidServer/node-solid-server/issues/1672#issuecomment-1059452233, when somebody has shared their data hosted on NSS with me, I can't access those data with a web app of my choice, I have to use the same web app they used.

This limits usefulness of otherwise interoperable apps that work on top of any kind of social non-public data.

In comparison, CSS doesn't use acl:trustedApp, and I can use an app of my choice to access the data shared with me.

Has this been discussed already? Is this a desired behaviour? It looks to me like it's an unfortunate side effect, since it limits one of goals of Solid Project[^personal]: People can choose which app they want to use.

[^personal]: as I understand it

Commencez par examiner le commentaire lié de l’issue 1672 et le comportement de acl:trustedApp dans node-solid-server, puis comparez-le au comportement CSS décrit ici. Déterminez si cette restriction est intentionnelle et définissez le comportement d’accès attendu avant d’identifier l’implémentation ACL concernée et la validation nécessaire pour corriger le problème.
