This is indeed one of the greatest suggestion I have heard in a long
time. Having people add "Part of the Wikimedia Movement" would benefit
both parties. All of us here I think support free knowledge wherever
it is found. Allowing our GLAM partners to use this wording and those
who are actively collaborating with us would be a start.
