For those who do not wish to participate in the Bozja content, yes. However, relics will be doable inside this instance through currently unknown means, but I think it's safe to say that things such as critical engagements, among other things, will reward relic progress or something related to it in the Bozja zone.

I doubt that as I believe Yoshida said you don't need to worry about Lost Actions if you're not interested and those are needed for Critical Engagements (or at least, the 1v1 portion).
