hrm.... I do this occasionally with some other folks on a project. often it's fe/be concerns - one person needs something added in a payload, for example. Working in their same branch to add that for their environment/branch was much faster than trying to coordinate a series of other changes/branches. It's not something I/we do a lot, but the few times we've done it in the last couple of months people have really liked it, and seemed to feel like we were making faster progress somehow.
