Hoi,
There are different transliterations per language pair.
When you include Wikidata in the mix; Wikidata should in my opinion support the transliteration from Russian to English according to ISO for its label. Anything else including whatever Wikipedia likes may be an alias.
Your point about confusion is the same as with standard metrics. Napoleon did us a service by moving to the metric system, It is sad that he did not conquer Britain so that we are now stuck with something that confuses the hell out of me when we have to deal with whatever you lot have..
Thanks,
