My expectation is that there will be a relatively small group of people in this practice area who will be speaking with each other, comparing notes and developing best practices. These are the kinds of things we've recommended be done, certainly, to ensure the professional development of all the people working in this area.
In a way, the likelihood of a relatively small number of people being involved has a downside, in the sense of access. It might be very hard for people to get an assessment for MAID in this context, but it also means that a small group will be able to professionally develop and compare notes, and, in so doing, address concerns about inconsistency.
