Yes, agreed. Though that's what I meant by "in part": when you read the threads, they derail when Kent takes potshots at other filesystems ... whose developers were CC'd in the mailing list.

To be honest, some of those reactions did feel a bit out of proportion; I am not entirely sure if there could be other reasons for blowing Kent's attitude out of proportion: (Like, does someone stand to benefit that a COW-filesystem without too many sharp edges isn't shipped?).
