Implications of not enabling STUN's CHANGE-REQUEST

[KNC]

Hi all,

From the docs, I see that supporting STUN's change-request requires 2 IP addresses that are both public (i.e. NOT behind a NAT, like in the case of EC2). If I'm building a WebRTC application and looking to support enterprise users who are often behind restrictive firewalls, what are the implications of not supporting the change-request feature? According to this post, there are no drawbacks - can someone please confirm that?

Thanks,

KN.
