Unless I misunderstood, GP mentions that the problem stems from WebPKI's central role in server identity management. Think of these cert lifetimes as forcefully being signed out after 47 days of being signed in.

Not necessarily. OP mentions, more certs would mean bigger CT logs. More frequent renewals mean more load. Like with everything else, this seems like a trade-off. Unfortunately, for you & I, as customers of cert authorities, 47 days is where the now the agreed cut-off is (not 42).
