Invalid initial SQLEXPRESS configuration

I was getting "The configuration of the AdminConnection\TCP protocol in the SQL instance SQLEXPRESS is not valid." warning in the event viewer every boot.
I found the solution in Straight No Chaser's post from Friday, March 09, 2007 7:47 PM here.
So, one should just change
"TcpDynamicPorts" in
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer\SuperSocketNetLib\AdminConnection\Tcp]
from 0 to, say 1433.

So, this looks like a very long-standing problem.

My question is - why default value is 0? It can not be valid, could it?
Shouldn't there be a patch to troubleshoot the issue?
