Yep, exactly - by "that first set" I meant the 00-1A group, could have been clearer. Whatever the smallest rollout bucket is, that group is guaranteed to have every single feature.

This was quite a while ago, but I think the actual case we noticed this with was several features released to 50% of the userbase - so every single user either had all or none at once (unintentionally)
