CRLs are pretty difficult to scale resiliently, though, for a number of applications. Same problem that led to OCSP stapling after OCSP became a thing. With CRLs you can at least take advantage of a CDN of some kind, but there are tradeoffs with your ability to operate a CRL securely doing that, too.

CRL in the driver install flow implies being online (at some point) to install drivers too. As we move into the future it’s hard to imagine not having Internet access, but we also don’t design Windows. It’s definitely a case they’ve considered, though I did see mention of a timestamp server in this thread (I don’t know much about Windows signing, just X.509 PKI in general).

Are driver CRLs any more challenging than the virus definitions already distributed through Windows Update?
