Not exact but a quick glance there are 200 votes so far with US is highest, followed by German, UK and Spanish for the top 4 which comprise probably around 90% of all votes together. Everything else has between 3 to 20 votes each combined with first and second choices so not a lot really. Things with less than 10 vote was dropped for now.
So more or less I took a leader language and then grouped it with the closer related ones that have some voting presence.
Based on current results, I was thinking to restructure the language packs to:
PACK 1:
US/GB/JP (Roman only) language specific keys
PACK 2:
DE/NO/DK/SF language specific keys
PACK 3:
ES/IT/PO language specific keys
PACK 4:
??/TBD based on need
Will continue to adjust based on voting where needed. You might notice a new addition here (lot of write in votes for) which is JP Japanese layout though will only have latin character. I see many board like that without actual Japanese legend so I can guess it would not be a problem for you.
