I agree that it's quite limited compared to, say, text-transform: uppercase, but is far more widely usable than, say, hiragana to katakana.

For hiragana-to-katakana, I asked about this idea to several Japanese authors before but none of them wished to have it. It was not comprehensive research, but I think using hiragana/katakana distinction for stylistic reasons is rare, and even when used, it's a bit different from other styles such as bold, italics, underlines, or emphasis marks. I guess the closest thing in English is double-quoting a word to emphasize.

U+2014/2015 could be a good use case, but you can't switch styles based on fonts, so the feature isn't useful by itself alone.

I could be wrong because I don't have good idea on other examples, but I'm seeing this in the following perspective:
1. Are the requirements real, from real authors using the language in their real life?
2. How much are implementers interested in implementing them?
3. Is it worth to delay the CSS Text Level 3, or okay to postpone to level 4?

"Full-size-kana" suffices both 1 and 2, and it will not delay the spec as it was already defined.

Do other examples suffice any of these? I don't have answers, so I believe postponing until we know better is the right thing to do. Do you, or does anyone in this ML know?

It all depends on the perspective, but I would say the need for full-size-kana is indeed quite limited. First it is specific to the Japanese language.  
Japanese, it is limited to documents using ruby. Then, it is a stylistic
some authors will actually prefer the small size kana.

It doesn't mean there is no real use case, but it is a specialized one.

It is the most prominent specialized use case we currently have. I think it would be a good opportunity to use it to drive a generic solutions that can benefit others.

A few other specialized used cases have been mentioned. Of course, they are all relatively minor, but that's the point: since they are unlikely to be addressed individually, trying to aim for a generic solution that solves all in one go sounds better to me.

A few examples, either already mentioned or reasonable to expect:

* Removing accents. This cannot be solved properly in the generic case, so the WG has (rightfully) rejected a hard-coded text transform to do that.  
But in more limited contexts, it would often be perfectly doable for authors to define a custom rule that removes accents the way they want it.

* Hakon has mentioned mkhedruli to asomtavruli http://en.wikipedia.org/wiki/Letter_case#Other_forms_of_case

* hiragana to katakana: the mapping is easy to determine, and this could be desirable once in a while for stylistic reasons

* mapping U-2014 to U-2015 (or the other way around), as mentioned in the writing modes discussion.

* ſ (long s) to s
