You are refreshingly optimistic. :)  Have you read 3GPP specs recently?  In theory their behavior should be self-limiting too; but it works in their closed single-vendor environments on day-1, then breaks on day-2 when the environment grows or another vendor is added.  And since the new vendor being added is the one with motivation to make things work, the new vendor is the one that will add 199 support.  Then one day the customer will want to connect their network to others, and boom.

If we can't think of any legitimate use for an option-tag in Require, why should we allow it?
