I think that'll depend very much on what the change is.  For new
functionality, sounds good; for bugfixes with testcases, sounds good.
For general algorithm improvements... how do you write a new QA test for
"Use the inode tree for finding dirty inodes?"  Or for that matter, my
remaining 2 shouting-removal patches ;)

Sounds awesome, for serious contributors.  I'd be happy to use it, too ;)
