This reverts commit dd66f235ec.
This changed the core servers API without doing it as an API extension,
so it's not an acceptable change as written.

The extended status extension was testing list instead of get and the
extended server attribute extension was misnaming its sample files.
This makes the names of the samples consistent.

DocImpact: The api sample site may need to be updated as well
