sdefresne: could you elaborate on what needs to be converted with |prefs::kSigninAllowed|?

Hi Antonio,

Apologies for the greatly-delayed response here! Sylvain and I chatted, and the answer is that nothing needs to be done; this bug was filed before we changed direction to have accessing the pref be the long-term direction for determining whether signin is allowed.
