I see that route context is not available on the on* route methods. Is it only intended for the loaders? I'd like to use route context as my dependency injection mechanism for route behaviors like onCatch

could maybe be passed in as optional?

You mean in the sense that some code in tanstack router could fail before getting to user-provided code such that the context isn't available?

no it could be that your beforeLoad throws for example and then route context is not (fully) availabl
