You are right in general. Most open core tools do not let anything enterprise like into community versions. However, Gitlab is somewhat different. For example is that it lets you have LDAP/AD integration in core version. Compare that to lets say Mattermost which doesn't. And yes, I need enterprise stuff, I just don't need enterprise stuff currently in Gitlab. Looks to me those stuff are created for really big teams and really big multinational companies. My company is 1200+ employees big with IT having around 70 people, and in that context I don't miss anything. Futhermore, some enterprise features finish in core after some time. I have never witnessed the opposite in Gitlab.
