I do work in quite a number of countries with respect to regulation. Where there is representation of the high-incidence groups of individuals with disabilities and specific groups that have well-organized advocacy groups, what tends to happen is that there are always individuals with disabilities who are left out.
I agree completely that we require representation of people experiencing disabilities, but we also need to continually ask who we are missing and who has not had a voice at this table. Quite frequently, for example, individuals who are non-speaking and low-incidence individuals and are part of very small minorities do not get to speak.
Also, the usual groups frequently go from one consultation to another, resulting in consultation fatigue, and there is repetition of specific opinions. I think we need to be inclusive in how we include individuals with disabilities.
