I don't have much of a horse in this race as I'm sort of in the grey area between YAG and YAG-emeritus these days (for reasons of schedule, not age) but I haven't seen much on-list discussion of this idea, so I wanted to pipe up to say I support it. I don't know what it's like to have "step" language when one can't step, but the change couldn't hurt. Additionally, the idea of stepping up and back seems to be frequently associated with how much someone has the figurative talking stick, and the idea of taking and making space seems to encompass more than just amount of talking, but other ways that space is shared, such as leadership, including other perspectives, etc.
