It uses a different database format than the current NetBSD db
library.  Why go through the pain of changing database formats just to
sync with a library which nobody is really maintaining?

(Whether krb5 db2 is compatible with Sleepycat db2 I do not know.  I
suspect it's not at this point, so we wouldn't even get compatibility
with them.)
