This is the same for all features no? If customers need additional human support for SSO then that can be charged separately. In my experience most customers can get it working with no hassles or have hassle but their own tech resources figure it out. Few need to get support. As a feature it is probably less work to implement and maintain than the simplest of product features. YMMV if you have a complicated integration but if you just want to sign people in and assign them to a group for security it isn't hard. Maybe we are talking cross purposes? I am talking about SSO with SAML and IdP rather than OAuth. I suspect the reason for the SSO Tax is it is an predictor of "does this customer have money". Customers with more money to spend and absolutely need SSO to meet their policies will overlap alot.
