Fair point, yes. I've just added a new testing CDs key for automatic

pub   4096R/09EA8AC3 2014-04-15
      Key fingerprint = F41D 3034 2F35 4669 5F65  C669 4246 8F40 09EA 8AC3
uid                  Debian Testing CDs Automatic Signing Key <debian-cd@lists.debian.org>
sub   4096R/6BD05CFB 2014-04-15

and some extra code into the build scripts to use this key for the
daily and weekly testing CD builds. Starting from the next daily build
tonight, this should happen automatically now.
