Dear Ryan! Thank you for sharing this information with us. Will this also have influence on Google’s concept of individual crls per certificate (e.g. http://crls.pki.goog/gts1c3/fVJxbV-Ktmk.crl for crt.sh | 7340166965<https://crt.sh/?id=7340166965>)? I like this concept of extremely sharded CRLs a lot since it effectively keeps the CRL size under control but at the end it seems to me to have the same privacy issues as the OCSP responder.

These can be exposed accidentally (e.g., via data breach of logs) or intentionally (e.g., via subpoena). This is part of why Chrome doesn't do OCSP checks for Domain Validated (DV) or Organization Validated (OV) certificates by default, and starting in version 106, Chrome won't do them for Extended Validation (EV) certificates either, to better protect users' privacy.
