Tanstack Router docs are missing documentation present in Tanstack Start docs

Recently we switched from React Router v6 to TanStack Router for our React application. We were seeing some unexpected behavior around error boundaries, but looking through the Router documentation I couldn't find anything on it!

Then i found it here in the Start docs, and here deep in Data Loading in the Router documentation.

As a developer I sort of expect to see a top-level section in the docs around Error Handling, like in the Start documentation, or under the Routing section. Just wanted to give some feedback on it. Sorry if this is the wrong place for that.

Commencez par comparer la page consacrée à la gestion des erreurs de TanStack Start avec la section Data Loading de la documentation de Router sur la gestion des erreurs. Identifiez la section de navigation ou de Routing de la documentation de Router où la gestion des erreurs est attendue, rendez les indications sur les Error Boundaries accessibles à cet endroit, puis vérifiez les liens et la formulation qui en résultent sur le site de documentation.
