[keycloak-dev] Should we allow response_type=token ?

[Marek Posolda]

Question about https://issues.jboss.org/browse/KEYCLOAK-2351 . Should we 
allow response_type=token ?

Basically OAuth2 allows that [1] but OpenID Connect doesn't for implicit 
nor hybrid flow to use response_type=token alone without "id_token" or 
"code" [2] [3] .

I am fine with support response_type=token, however doesn't we break 
OpenID Connect specs then? Or should we have option (either on/off flag 
or list of valid response_type combinations) in configuration to specify 
whether it's allowed or not?
