AFAICS v9 (unlike v10) supported both of the above cases.

I wrote that section and I certainly wasn't considering Cyrillic aspects
at that time (IIRC it was written even before Mike did the major update
for transliteration rules at the end of 2015). The context back then was
mostly about handling Latin letters like Ã
, Ä, Ö, Ø, etc.

We certainly can decide here what's the best course of action, we do not
have to slavishly follow some old bug report when deciding the direction
for the implementation. But I think I've made my position clear by now
so I'm not going to repeat it anymore.

In any case once your patch lands I'm going to submit a follow-up patch
for fi_FI to make it compliant with the applicable national standard
(SFS 4900) which defines how to do Cyrillic transliteration /
transcription in the context Finnish.

Thanks,
