We are agree with the idea to reduce certificate lifetime as soon as possible.

Several the results of these discussions, and barrier to change, are evident in the BRs themselves (issuance from a root, the internal server name deprecation date, etc). By eliminating long lived certs, the Forum eliminates one of the major obstacles in improving the industry, permitting the Forum to become the primary proponent for improvements instead of the browsers (ie, instead of Microsoft announcing that SHA2 is required for all certs three years from now, the Forum could have passed a BR requirement to the same effect).

During the discussions, the group estimated that 50% of the problem certificates resulted from stolen or compromised private keys.  I imagine the problem is just as bad for SSL.  Add on top of that the fact that five-year old information is extremely stale and has likely changed.

Or is the concern more theoretical?

We all understand that CAs want to nail a customer for as long as possible and make a difference by issuing certificates for long periods of time (irresponsible) because others won't do that - but since this requirement would be applied across the board I believe there will be no competitive disadvantage to any of them.

Being able to act faster and get rid of possible problematic certificates within the time-frame of 3 years without the need of revocation (which would result in a another outcry anyway) is probably a worthy goal. With the current upcoming changes it appears to be a golden opportunity to achieve that.
