Level 2 features should be strongly recommended and levels 3 and 4 features should be marked as "at risk"

Fantasai's blog article about ruby markup design is still very useful. In particular, it shows four possible levels: Level 1 (Simple Ruby), Level 2 (Multi-pair Word Ruby, Level 3 (Double Ruby) and Level 4 (Full Complex Ruby).

I think that level 2 features should be strongly recommended and levels 3 and 4 features should be marked as "at risk". Such a change make this extension work more relevant. In its current form, I am not sure if developers think this draft really relevant.
