The suggestion of a "universal language picker" assumes that language names are uniquely identified in that way. This is just not true. The assumption is also that there is a need for a language picker on Commons. The language should be based on the language of the user interface the only possible reason why this would not work is when Commons decides to allow for anonymous uploads.
We are asked for an opinion and having a language picker makes sense in the user preferences. Allowing for a global default would be a huge usability improvement. When it is also possible to override them locally, it would be bliss.
