If I see it correctly that's not quite correct either. The old 
silentoldconfig does a few things differently than a normal config target, 
because it's a special target called by Kbuild when needed:

- bail out if input is needed but stdio is not a tty
- silent mode
- update .config only as needed
- always update autoconf

With the change to make the silent mode the default, the "silent" name has 
become a little obsolete and should probably be renamed, but whatever the 
name above actions should still be done if called by Kbuild internally.

bye, Roman
