code would be simpler if this was non-optional and the JS test for warning
presence was install_warnings.length > 0.

But it seems that chrome://extensions page only shows installation warnings for
unpacked apps/extensions. So I choose optional.

The effect would be identical, unpacked doesn't come into it. I will comment in
the other place.

Done.
