Do you know why the official recommendation is ext4 instead of xfs?

Based on official practices, I guess one reason is that ext4 is relatively stable and has higher security, and another reason is that ext4 has an advantage over xfs in reading and writing small files. TiDB storage files happen to require concurrent reading and writing of multiple small regions.
