Are you asking me if _I_ find it useful?  It is not a very useful
question to ask, as I've taken things that I do not find useful
myself.

Having said that, I do not see me personally using it.  You keep
claiming that committing without ever materializing the exact state
that is committed in the working tree is a good thing.

I do not subscribe to that view.  

I'd rather do a quick fix-up on top (which ensures that at least the
fix-up works in the context of the tip), and then "rebase -i" to
move it a more appropriate place in the history (during which I have
a chance to ensure that the fix-up works in the context it is
intended to apply to).

I know that every time I say this, people who prefer to commit
things that never existed in the working tree will say "but we'll
test it later after we make these commit without having their state
in the working tree".  But I also know better that "later" often do
not come, ever, at least for people like me ;-).

The amount of work _required_ to record the fix-up at its final
resting place deeper in the history would be larger with "rebase -i"
approach, simply because approaches like "commit --onto" and "git
post" that throw a new commit deep in the history would not require
ever materializing it in the working tree.  But because I care about
what I am actually committing, and because I am just lazy as any
other human (if not more), I'd prefer an apporach that _forces_ me
to have a checkout of the exact state that I'd be committing.  That
would prod me to actually looking at and testing the state after the
change in the context it is meant to go.
