Quick first story grooming:
Commons have a bot that will try to fix dates. There is no guarantee that dates on a specific wiki always uses the same format. So I think it is better to leave the converting to the bot on Commons instead of making the code of FileImporter more complicated. I can of course not forbid the team to implement it but I would support if they decide not to do it (to close this as not done).
As argued above this is a hard problem. A general solution that works with all Wikimedia languages would require an entirely new sub-system in the FileImporter codebase. More specialized community-maintained solutions exist.
