Impact

Read only calls between contracts can generate smart contracts results. For example, if contract A calls in read only mode contract B and the called function will make changes upon the contract's B state, the state will be altered for contract B as if the call was not made in the read-only mode. This can lead to some effects not designed by the original smart contracts programmers.
