Depends what you mean by "more reviewed".
More eyes looking at the specs? Probably yes. More critical analysis by
senior technical architects? Probably not.

Again, depends upon what one means by running code.
Certainly there were early prototypes of OSI modules, and even running
products. Clearly, that was not enough. In contrast, the Internet code was
deployed and used in a running service, with increasing scale. So the
distinction between prototype and production is probably of fundamental
importance. (I think that Dave Clark really meant "running service" when he
said "running code".)
