In reply to Rupert.

As a long-time follower of the open accessibility issue on the Select2 repo, my understanding was that there was little confidence that Select2 might adopt the changes WC introduced in selectWoo simply due to a pattern of inactivity for ~6 months.

WC didn't fork it willy nilly, they forked it because it was the only way they could ensure the a11y improvements could become widely available.
