Is anyone aware of any up-to-date data on this btw?  I've had
discussions with the browser makers and they have some data, but I
wonder whether anyone else has any data at scale of how often users
really do run into cert warnings these days. They used to be quite
common, but other than 1 or 2 sites I visit regularly that I know ave
self-signed certs, I *never* run into cert warnings anymore.   BTW,
I'm excluding "mixed content" warnings from this for the moment
because they are a different but related issue.
