el-latn, ru-latn, and related possibilities

Guys, sorry to be the odd man out yet again, but we should first run through all the use cases before deciding that transliteration can be pushed down the stack. This argument sounds to me more like a rationalization for continuing with 3066bis than to really address the question.
Text to voice is important for accessibility. Identification of the transliteration scheme would be a prominent requirement and perhaps therefore ru-Latn is not sufficient and should not be recommended as adequate.
Also, if we buy the argument that script was important enough to break compatibility with lang-region, and to instead associate script with language as lang-script-region, I would think we would want transliteration to also be tied with script and not go after region.
Something like zh-hans-pinyin-cn rather than zh-hans-cn-pinyin.
What am I missing?
(yeah, yeah, marbles I know...)
