Look at clsact. It creates blocks in exactly the same way.

The block binding mechanics are not new. The patch just reuses them. If
you are unhappy about how this is currently done, I too would see merit
in creating a block explicitly, like with chains. But it has nothing to
do with this patchset, which would just naturally pick up whatever this
new mechanic is.
