You are right, the deadline has passed. However, this Change was announced in advance to the Change wrangler and it seems to be the kind of a Change we need to have. Originally it was planned as a Self-Contained change, however as it affects the building infrastructure it was turned to System-Wide to make sure it attracts wider audience.
I hope, the community understands this exception.
