For some people it is part of identity and since we already have several different options for in-game romances, why not include it for protagonist as well?

Sure, but this way player would not have to go through the extra dialogs if player does not want to. It simplifies things and clearly indicates what game do you want to play.

Tastes are different - I, for once, prefer more proactive companions. Again, as a compromise (same with player-sexuality) it is fine and can be made in a way, that once you clicked a special dialog options - romance begins and LI is active, but if you played DA2 (DAO too, actually) you should remember how many problems misclicks created. With the flag system misclicks simply would not happen.
I do not see any drawbacks with the flags, only simplification and an option for everyone to get a better game.
