That was my understanding and also my plan, but it does not seem feasible to force this as the vendor of the software. If the customer says they need SAML at some point the business side will require that it is implemented. I do want to try and get as far with only OIDC as possible, but I am a bit worried that some larger customer might just bulldoze through because they only want SAML. Might be much more likely for on premise cases, if you're in the cloud you probably use an identity provider that supports OIDC already.
