Is it considered weird to drop into combat grid and initiative order to handle action strategy like trying to dodge around a guard patrol, even if nobody's been stabbed yet and nobody might get stabbed at all?

Speaking of delay, I know that's not part of 5e (it was in 3.5), but if we can't have ready action could we at least have the delay option? A lot simpler to implement and it'd at least help with the situations where you would have been better off at worse initiative.
