Kerberos ccache in /tmp, why not kernel keyring?

Hi,

any idea why debian and ubuntu do not use the kernel keyring as the
default storage for the kerberos credentials cache? We still use files
in /tmp, like /tmp/krb5cc_1000 for a user with uid 1000.

Is it because of heimdal compatibility? Its keyring support was merged
in 2018[1], but doesn't seem to be in a release yet.
