I would neither do 4 (it's good to have newer nspr/nss, see #824872) or
2 (would deviate us from stretch, jessie and upstream). Given we don't
find other regressions it'd go for 3 or 1.

Although chromium is unsupported there might be people using it to
access "trusted" hosts for things that dont work with Firefix (at least
VCenter comes to mind).

Did you check what upstream chromium did when they updated nss? Maybe we
can cherry-pick a simple fix from there? If not this just leaves us with 1.
