Would that mean, I have to identify initially to join a mint. But afterwards I can transact as private as usually with cashu?

Depends on the mint you use. We want to give the operator the option to limit who uses their mint.
On privacy: this hurts privacy for peg-ins and peg-outs for example. Even if there was full KYC, ecash is still a lot more private than a normal custodian. The provider doesn't have a view into your wallet, can't take your ecash, and can't stop you from transacting with others.
