But I maintain that the end result is better than the fragmentation

Me? Radix tree based approach? That approach is in the kernel. Do not
create a solution where there is no problem. If we do not want to
support large blocksizes then lets be honest and say so instead of
redefining what a block is. The current approach is fine if one is
satisfied with scatter gather and the VM overhead coming with handling
these pages. I fail to see what any of what you are proposing would add to
that.
I'm not just making this up. Fragmentation. OK?
