I agree 100% with your arguments against supporting group-based policies. :) I guess
people doing authorization based on groups are essentially using roles, they are just
calling them groups. Keycloak can perfectly cover that case by using roles. The only
potential difference I see is when there is something like composite roles or composite
groups. With a composite role, you get all the subroles. With a composite group, you are
in all the parent groups. However, offering this opposite direction (and adding composite
groups) comes at the price of making it even harder for people to decide what they should
(and do it correctly) so I don’t think it's really worth it.
I do like the current RBAC way as it is a very clear concept. You can still switch to ABAC
if RBAC does not cover your case...

Subject: Re: [keycloak-dev] Group Based Policy
Forgot to add something to the discussion.
I'm not 100% sure if we should have a group policy though. Reason being that
groups are usually administrative things to group a set of one or more users and
usually they are not really suitable for authorization. For instance, with current
design you could enforce access based on groups as long as your groups have a
specific role which you can use in a role based policy. In this sense, roles are
definitely more suitable for authorization than groups.
