I think we're talking about the difference between:

a) indicating that, as of time of generation, the frames sent represent a complete set, but that it might be added to later
b) indicating that the set is complete for the rest of the lifetime of the connection


If so, (b) seems like the client is committing to never change the set after a certain point, with the only recourse being GOAWAY. I crafted (a) like it is because I think the intent is to avoid a recipient using the set when more are in flight towards it; of course, it doesn't completely avoid the race condition, it's more like a hint.
