So, that's the other side of the argument? I assume there was at least a reason they specced it this way originally, even if under comparison those reasons wouldn't have held up. Was there any justification, or was it literally ignored?

It was considered a non-issue, since it's easy to work around. See https://github.com/http2/http2-spec/issues/61

Since HTTP2 is a client->server protocol, the server can close whenever and the client can just open another one.
