It's a real shame. OCSP with Must-Staple seemed like the perfect solution to this, it just never got widespread support.

I suppose technically you can get approximately the same thing with 24-hour certificate expiry times. Maybe that's where this is ultimately heading. But there are issues with that design too. For example, it seems a little at odds with the idea of Certificate Transparency logs having a 24-hour merge delay.

Also certificate transparency is moving to a new standard (sunlight CT) that has immediate merges. Google requires maximum merge delay to be 1 minute or less, but they've said on google groups that they expect merges to be way faster.

The log is not really for real time use. It’s to catch CA non-compliance.
