I don't think that's a plausible risk.  That said, in the next
year or two, with soon 5 years of implementation experience behind
us, it may be time to publish an update the clarifies the murkier
corners of 7671/7672 or even a pair of bis rewrites.  Though it
might be tricky for lack of a working group in which to do so.
Perhaps UTA could work, though it too might be shut down by then.
