FWIW: a friend who works in the IT department at another school said almost all schools will disable the checklist for everyone a few days ahead of the decision date. He said the reason is technical: every time someone logs into the portal it requires a call to a database server to retrieve the information required to display the checklist (i.e. to get a list of what items to show/not show). With a large increase in portal traffic in the days ahead of decision day it creates stress on the servers, so they disable the checklist.
So it’s not a sign. The checklist should go away for everyone.
