Actually, in Belarus, they also use 2 languages: Russian and Belarusian. Nevertheless, as the vast majority of roadsigns are in Belarusian, they recently switched all toponyms and road names to Belarusian (which is more logical from a frequent traveler point of view).
int_name in English? I'm afraid it would make no sense: we already have the name:en tag for that. For example, when you use OSM-based maps (like maps.me), names that will appear by default are name=* and int_name=* if the name:en tag isn't filled.

So you have a passion for mountains? :D One of my Polish friends is such a passionate that he visited neighboring Kyrgyzstan a few months ago :D 

P.S.: What do you mean the OSM community doesn't accept those changes?
