The first time you contact an ssh server, you're presented with a fingerprint and asked whether you want to trust the server to be who it is, based on this fingerprint. Blindly, i might add. If you're at least a bit concerned about (usable) security, this should send a few shivers down your spine; how the heck are you supposed to know whether this fingerprint is right or not.
If you're managing your servers with ansible, this query can be inconvenient, as it stops your flow at some random place and it's not entirely clear where it will commence.
