I’ll be sad to run inetd again on systems so that I can run a wrapped 
sshd.
Like others I feel that adding firewalls to a machine simply to filter 
sshd is not an option and whatever else openssh itself has offered in 
the past never sufficed.

I am also worried that the change will make a lot of machines 
unprotected upon updating to 13 if there is no big red warning flag 
before the install.


I do understand the burden of maintaining a local patch (we lost the HA 
patches from base this way already).

Given the port already does maintain the patch I am wondering what 
“security guarantees” we provide for the port compared to the base 
system (ignoring possible security updates) or why the patch cannot be 
included in base?  Compared to the HA patch, this one seems to be 
sillily small..
