This is not something we should add IMO. As Bill points out the whole idea
is to not expose credentials to application. I'd rather see something that
works without exposing credentials to the users. Could do a redirect with
re-auth required. Could require just adding otp on re-auth. Could possibly
do a popup with embedded login from KC. I'm sure there's cleaner ways than
the applicaiton collection OTP.
However, it's perfectly possible to implement this using a custom rest
resource so if you really want it to do this then do it that way.
