That’s the judgement call to make and sometimes I don’t ask but assume when (i) it’s easy to change later, in other words a 2 way door (ii) asking will cause meetings, scheduling challenges (need to get everyone in the room!) and delay work and (iii) the people I’m asking might bike shed it taking up lots of their time and mine. It’s the developers discretionary power! Perhaps the colour of the capacitor inside the iPhone … you don’t need to run past Jobs (back in the day…)
