And in fact, looking at their code:

commit 21af504e8a8bcdded12c88c2e5ff4bef418313f2
Author: Love Hörnquist Åstrand <lha at kth.se>
Date:   Sat Jul 26 18:25:23 2008 +0000

    Add krb5_cc_[gs]et_config.

(Initially Heimdal used the realm name of the ccache's default
principal, but then it changed to use the X-CACHECONF: realm as in our
code.)
