I know GlobalSign has SHA-1 certs that expire in the future, I still stay block 
them.  There should not that many and one would hope that they are not even 
being used (much).  The browsers have been conveying degraded UI on these for a 
long time, so blocking them is the next logical step.  I don’t see the whole 
fatigue issue being so critical now, you’ve fatigued users for the past year or 
more so I don’t this as making the problem any worse.  Block them.

Sure, and I say we should solve global warming, income inequality, world 
hunger, P versus NP, and unicorn cloning.

Unfortunately, such statements ignore the part of the message I highlighted
"But this also demonstrates the balance that browsers face when charged with 
protecting their users - do we block access to these sites (as Chrome is doing, 
and as Microsoft will around February 15) or not? If we do block these sites, 
we run the risk of causing the average user to see too many of these messages a 
day, thus succumbing to warning fatigue, and causing them to ignore these 
warnings when their information is truly at risk. This makes everyone less 
secure - either through warning fatigue or through lack of automatic 
protection."

If you'd like, I'd be happy to find GlobalSign certificates that have this 
problem, and we can then have a public discussion about what specific 
communications GlobalSign made to these subscribers, and whether or not such 
efforts are sufficient for browsers to justify blocking them. Because 
effectively, that is what it would take to help inform and illuminate that 
discussion, given the current evidence.

I say go ahead and block them, they’ve all been warned and should be prepared
