Actually, what I said is that doing this is quite easy, and I've posted
the proof of concept script on multiple occasions.

The problem with that statement is that your perception is heavily
influenced by the fact that you're a developer. Way more than 90% of
mergemaster's users do only occasional upgrades, and need the script to be
simple and safe. Power users (like most of the developer community) should
be able to handle the kind of customizations that are most frequently
requested themselves, or crib them from a set of examples, that I'm still
interested in committing.
