This is a very good post!

Related: I had a Bulgarian co-worker years ago. She said growing up, there was wide-spread use of both Cyrillic and Roman characters for Bulgarian language. She said she was always able to express herself using either character set. However, I don't know anything about the cultural context of Russian. Naively, I assume it is strictly Cyrillic. It would be nice if some native Russian speakers can comment about transliteration systems used on PCs.
