Our longstanding offering won’t fundamentally change next year, but we are going to introduce a new offering that’s a big shift from anything we’ve done before - short-lived certificates. Specifically, certificates with a lifetime of six days. This is a big upgrade for the security of the TLS ecosystem because it minimizes exposure time during a key compromise event.

Interested amateur disclaimer!

Fast rotating certificates always more secure because the timeframe between beach discovery and system inherent revoke is shorter.

How big the impact in terms of real life is I can't even guess because of the (from my perspective) weird circumstances they must happen to depend on the certificate lifetime itself.

I guess it's just one of these "every but helps" factors more than specific use cases.
