You exaggerate.

Reiser4 does a very nice job of packing the tree tightly, which is
independent of seeks.  Ditto for compression plugin.
He merely needs to ignore some code, he is not harmed by it.  If he
wants to write a new block allocator, sure, why not, we have allocator
plugins yes?   His will just be simpler.....
