If OS vendors could get over their "not invented here" syndrome with respect to default file systems we might see something a little bit more sane than FAT as the one interchangeable format. This is necessary but not sufficient to make decent file systems widely available. Then we can start hoping for such trivial features to become available.
Everybody shops for the best filesystem around that they can use. The problem is, licensing is a problem.
In other times, the industry would solve this by creating a standard for metadata interchange, but one of the biggest players gets a too big to ignore amount of revenue from FAT, and is able to block any attempt at standardizing.
