I wish that SAML would stop being referenced as Enterprise oriented and that some SPs would stop providing support for it only in their highest payment tiers. As every company nowadays have G Suite or something similar, they almost certainly have an Idp ready.
It's the only thing that most SaaS things charge for now-a-days. Slack, Dropbox, Github Enterprise, etc. They know that regulated businesses have requirements to have SSO and things like this, so they can charge out the nose for it. You can go for a very long time with paying little to nothing for most of these services until you need SSO.
