Sounds like what DCE/DFS did. The Kerberos tickets where stored
in a well known location, with the PAG number as part of the file name.
/opt/dcelocal/var/security/creds/deccred_xxxxxxxx  where xxxxxxxx was
the PAG. Then the kernel could tell dced (something
like afsd) to fetch a ticket from the cache or even get additional tickets
and renew tickets. This also allowed DFS to use a separate principal
for each server. This is kind of what Windows does too with cifs/servername
principals. So it can be done.

Other applications could use the tickets in the cache bu seting the
KRB5CCNAME to point at the deccred_xxxxxxxx. So "Kerberos and DFS used the
same ticket/token storage mechanism."

It may not be dead, just turned out to pasture to early.
