I read the article about Let's Encrypt considering dropping support for OCSP. Does that mean I will have to disable OCSP Stapling?
The future of the OCSP is in discussion, no end date decided yet. I suggest not to do anything for the time being.
I'd recommend to "Watch" (e.g. subscribe using the bell icon I believe is somewhere at the top right) to the API Announcements category where any updates to the LE API will be announced.
