> Also there must be at least someone very knowledgable of Keycloak to give guidance to the rest of the team

this is why I said large team, you need people with knowledge, but on small teams you likely can neither hire them (if the team already exist) or have resource to spare on giving someone a lot of time to get into it. And having just one specialist would be very risk to actually you need 1.5-2 people. Things become worse if you also need to have plugins and are not a Java workshop at all (as even if you don't write them you should review 3rd party plugins).

Through I guess that doesn't apply if you only do very straight forward thing, like no multi tenant no fancy anything, then a small team work well. too.

I mainly said it can be dangerous as small new startups are often on a very very tight time schedule so the delays yo can run into if you don't have a Keycloak expert can be quite hurtful for them.
