Rollback is trivially easy; reverting a merge is as easy as reverting a squashed commit. It has the added benefit that any individual commit can be backed out automatically (in a squashed patch, that's not possible).

Having a feature repo to *work* on a patch is a great idea, I
interpreted the question as being about what the mainline history
should look like. The latter is where I strongly prefer the "atomic
feature commit" model.
