I read about that too.
While I do understand why they are doing it and what they want to achieve with it, I don’t think that that is the proper way to do it. While the “most easy” way, yes but I am not sure if its the best way.
Firefox built a whole revocation system, shortening certificates was not the easiest way, but it is what they are going with.
I think there was something called OCSP stapling and the revocation required another server to be run which had the advantage of being very quick to revoke certificates.
