Server 2012 is still in extended support, as far as I understand.

I agree that perhaps it's better to move to the new SCT, but there might still be companies that still run 2012 and rely on the availability of SCM 4 as a download? Maybe you have the option to add a notice that SCM is superseded by SCT on that download page and leave it up until 2012 support ends?
