> The argument about Windows not having a single, central dentry cache doesn't hold water
This was more about cache coherency, and it's not an argument, it's a trait shared by every other Linux-over-X implementation (UML, coLinux). It is fundamental to solving a problem users want - seamless integration, i.e. no opaque ext4 blob. Why doubt the reasons given by Microsoft, when they match observations not just for WSL but every other system in the same class?
