The answer is subjective, depends on the nations one has for each passport and their diplomatic ties. There are also complications on who takes jurisdiction during crisis (like disaster or war) since one country will argue on who should take control of repatriation. For example, when the Iranian conflict started: evacuation flights issued by let's say by Germany for German citizens, what happens if an British person also has a German passport (a dual citizen of a EU and a non-EU country), wouldn't the UK also say they're also a citizen.

This is what I mean, during certain situations or a crisis: who takes charge if the individual is from 2 nationalities which may cause a dispute between both sides? Like, if Britain said "This guy is British" (refering to being stranded in UAE during a drone attack) but Germany recants "He's also ours". Although the repatriation flights are intended to be for German nationals stuck there, despite the individual also having a British passport even though Germany considers this person a German citizen by their second passport.
