I think there is confusion in the word "detail". Moire affects identically repeating patterns and can prevent good visualization of detail in those repeating patterns (suspension bridge wires, some architectural elements, fabrics) but random fine detail such as is usually found in nature will be fine and will not require an anti-aliasing filter. So I think the blanket statement of sharper more detailed images is too simple, especially as many (most?) mirrorless cameras no longer have anti-aliasing filters. Moire is much less of a problem for most images as sensor resolution has increased and simple software solutions are available if it occurs, so I do think that the X-trans sensor's raison d'etre is not all that strong these days.
