You are absolutely right. This is not critical. But desirable. I would like to see the list of the development team. Examine who they were and where they worked before they came to this project. All this gives me a picture of the prospects of this project. All the same, I'm going to invest my money here and I want to know who I give it to.
Of course, this is your legal right. But sometimes teams basically want to remain anonymous. Even the creator of Bitcoin remained anonymous. Therefore, I do not see anything wrong with that.
