pkg_cutleaves works interactively by default and can be aborted at any time. 
I'm of the same mindset, still pkg_cutleaves does it's job very well:
- Reads config file of leaves to keep, so you don't have to answer the same 
questions on each run
- Builds a list of current leaves, asks you whether to deinstall and *then* 
deinstalls those leaves (not between each answer - fumble finger protection!)
- Gives the option re-evaluate leaves after a run, so you can optionally 
remove dependencies of deinstalled packages (recursive, yet not recursive).

I typically run it as pkg_cutleaves -xg, so that new "Kept" packages are added 
to the config file automatically.
