Describe the feature you'd like to request

Allow creating custom hooks that have the same types (for both arguments and return) as when using useQuery.
Simple example, assuming I have a TRPC server that provides a route trpcClient.user.searchByPseudo(input) where input is a string and the return is of the type User.

const useSearchUserByPseudoQuery = <
  T extends Parameters<typeof trpc.user.searchByPseudo.queryOptions>[1],
>(
  input: string,
  opts?: T
) => {
  const query = useQuery(trpc.user.searchByPseudo.queryOptions(input, opts));

  useEffect(() => {
    // doing something with query.data for example
  }, [query.data]);

  return query;
};

Unfortunately that new hook won't have the same types inferred for its return as when using the original hook:

const MyComponent = () => {
  const { data: dataFromUseQuery } = useQuery(trpc.user.searchByPseudo.queryOptions('foo');
  // dataFromUseQuery type is as expected: User | undefined

  const { data: dataFromOurHook } = useSearchUserByPseudoQuery('foo');
  // dataFromUseQuery type is incorrect: {}
}

Describe the solution you'd like to see

I've no idea as to how to do it ! I can just say the types should be kept. I've tried many ways, but I haven't been able to find one, so I assume a change is needed in @trpc/tanstack-react-query.

Describe alternate solutions

There are no alternate solutions, the return type should be kept.
