Meh, who knows that they are using 'secure' search just because they are signed into their Google account? Fair enough if people were explicitly choosing that, but it's just a side effect of being signed in.

Also, note that Google is blatantly still serving you ads on the basis of what you're searching for, just no longer sharing that with Analytics users. So the privacy win is minimal.
If everyone using Google search was signed into a Google account when searching, then there would be no keyword data at all for Google searches in Analytics. Already, keyword "(not provided)" is the second largest category in the organic traffic for my site.
This is a classic sign of a company that is the opposite of lean/nimble, falling over itself to the detriment of its customers...
