I would expect that it's actually a requirement and that you could get fined for that in an inspection. 146 people died in club in France due to inwards doors in 1970: https://en.wikipedia.org/wiki/Club_Cinq-Sept_fire https://en.wikipedia.org/wiki/Club_Cinq-Sept_fire I don't know the scale of the fine but using inwards doors are a big no-no. And similarly, electrical door must unlock themselves when losing power (unless special buildings like military or dangerous laboratories).
