Videos with the team should be good though, however ID not required for your own privacy and security.
Of course id is required. The can put their finger over the important parts to block them out but we need to know that the people we are dealing with are in deed who they say they are. Don't you agree?
Personally I think it's overkill, everyone has their own opinions and I respect that.
I never seen a project having to prove themselves on video showing their id.
If it were 2012/13 when there were a lot of coins with anonymous devs being released, I might have been a bit reluctant to trust any of those teams.
However the aeternity team seems open, they have names on the website, I personally know a couple of them.
Haven't seen token sale details yet, once I do and see how they are going to manage it I will also be able to make my own judgement.
They are also on telegram at
https://telegram.me/aeternity, again, personally I have no trust issues but if in doubt you can also reach out.
