If we have an InstallResource() for e.g. Plasma Dataengines already,
implementing it for language packs too should be trivial.
The specific collection of language packages etc. will then be handled by
the backend itself, e.g. for Debian we could reuse the existing script and
Yum could implement it's own solution for fetching languages too.
Having this in PK would be valuable for sure!

Kind regards,
