Looks good to me.

Yes, and I think that SI units like i18nc("mass unit symbol", "kg") should not 
be translated either?

I think they should still be case sensitive. Mg and mg are different units. 
But it's true that there's no need for multiple versions. Lower casing can be 
handled in runner. Runner now first tries to find perfect match and then 
startsWith match that can result multiple hits. If startsWith is 
CaseInsensitive it should work.

What other classes need changing (if not talking about SI units)?

So this could be:
    i18nc("unit synonyms for matching user input", 

This leaves "South Africa Rands" unmatched though.
