estark@, I haven't done any work on this yet.
emilyschechter@, how much of a "want" is this for M57?

To confirm: is this the "credit card" piece of HTTP bad Phase 1? The "password" piece was implemented separately?

This is core feature functionality and I think it should match across platforms, so should be prioritized over i.e. Q1 bug fixes, but I'm not exactly sure what else you have on the docket for M57 time frame -- can you help me understand (maybe off-bug) what we're prioritizing this against?

Nice! Great work :)

================================
TEST=Use an iPhone, not an iPad. First, enable the proper flag:
--------------------------------
1. Open the Settings app
2. Scroll to Chrome Beta/Dev/Canary and press
3. Scroll down to Experimental Settings and press
4. Scroll to EXTRA FLAGS (ONE PER LINE)
5. Toggle "Append Extra Flags" to ON
6. Set Flag1 to "--mark-non-secure-as=show-non-secure-passwords-cc-ui" (without the quotes)
--------------------------------
Test 3 URLs:
1) Visit https://badssl.com/input/credit-card/ and verify that the omnibox security has a green lock security indicator to the left of the URL.
2) Visit http://http-credit-card.badssl.com/ and verify that the omnibox security has a grey info icon ⓘ security indicator to the left of the URL.
3) Visit http://http.badssl.com/ and verify that the omnibox does *not* have a security indicator to the left of the URL.
--------------------------------
4) Set Flag1 (see above) to "--mark-non-secure-as=neutral" (without the quotes) and check that http://http-credit-card.badssl.com/ does *not* have a security indicator to the left of the URL.
