getting a random email address from a dedicated deltachat server is a new, optional feature. it didn't exist when i signed up. no matter. i am not using deltachat in a way that i need to stay anonymous. i am using it to talk to my friends. and if i wanted to i could create another account on the new servers. the ability to use a semi-anonymous email was always there. it's just a matter of finding a server for that. i am afraid though that the anonymity of the deltachat servers will be abused and they become targets of law enforcement.
