Currently buf size is fixed at 32KB. It would be useful if it could

Why is this needed? The real buffering is in the kernel anyways; this is
only used to reduce the number of write() syscalls.

This was introduced to buffer the transfered guests image transaction ally on the receiver side. The sender doesn't use it.
In case of intermediate state, we just discard this buffer.
