Linux systems are more than just a kernel. Does every program across the system now understand that direct comparison of strings doesn't work on filenames? Does every regex touching or analyzing filenames know that they must now be case insensitive? How long until people stop getting bitten by this issue?
That aside, inferring semantic meaning based on a few cultures at this moment in time is a dumb choice. There are tons of such language-specific semantics that could be implemented and the result is needing to memorize all those rules about when it does and doesn't actually matter (and arguing that only certain cultures and languages should have their own semantics encoded in the OS is its own problem).
