I don't think it's too inconsistent for MCU Tony Stark, depending on how they do it. He's always been someone who sees things from his perspective first and foremost. That being said:
1] He's always been open about his 'secret identity'.
2] If he is in charge of the registration, his hubris will will convince him that it will all go well when he is directing it. It is during comics Civil War that he becomes head of SHIELD. Tony Stark will believe *his* SHIELD is infallible.
