Not all that much has changed. SSL Pulse[1] shows that use of OCSP Stapling went up about 3% in the past 12 months, currently putting it at 25% of observed sites. OCSP Must-Staple is now available in Firefox and can be added as an extension to certificates issued by Let's Encrypt. No other browsers have plans for Must-Staple AFAIK. Otherwise, OCSP is still soft-fail for everything but EV in most scenarios. [1]: https://www.trustworthyinternet.org/ssl-pulse/ https://www.trustworthyinternet.org/ssl-pulse/
