-        The site is using outdated security settings that may prevent future versions of Chromium from being able to safely access it.
+        The certificate chain for this website contains at least one certificate that was signed using an outdated algorithm (SHA-1 with RSA encryption). This website should upgrade its certificates to avoid a downgraded lock icon.

This really makes it just seem like a capricious, unilateral decision "oh, we
took away the lock" - without any imparting as to why.

Instead of communicating "Hey, your site may break in 7 months", it seems like
we are now just saying " eh, whatever, no lock icon, nbd"

In the email, you said we should say more actionable things. :-P
Enough people already think our stance is "no lock icon, nbd". Except first
they're confused because they're not sure what causes the lock icon.

If you really don't like the emphasis on the lock icon, how about just leaving
it out? "This website should upgrade its certificates."
