Current text reads like it is requiring PKCE support even for the 
confidential client.
Do you remember the reason for it? Or is it just an editorial error?

John may have mentioned a potential attack that PKCE could help but I do 
not quite remember the details....

If it is an error, then we should fix it for the final.
