I mean I suppose, but I feel like limiting rp due to an unlikely event that someone will be able to get clericism and chi, or clericism and kani, or all three in an extremely unlikely circumstance, is kinda strange. No reason to limit rp like that. Plus, you can’t even use chi and clericism at the same time, you would have to pick one or the other, you would just be more versatile I suppose. But I don’t know enough about kani to comment on that.
edit: to add on to this, if you want to limit something, limit it irp. For example, irp I don’t accept chi students who are actively warriors because I don’t want them to stray from the path of hulian and abuse the magic. If clerics don’t want someone to use chi and clericism then they can just not teach chi monks, it’s that simple. No reason to restrict rp in lore via compatability unless there is a lore reason it should be restricted, in my opinion.
