It would be easier all round if MAP was 'Go-around instructions will be passed by ATC' especially in LOVIS.
I've lost count of the waste of time and breath briefing some complex go-around only to be told - 'climb straight ahead to x000' or somesuch.
Procedural environment go for the published version - radar environment, dynamic situation - leave it to ATC to tell you and that expectation should be published on the chart.
