Some templates are outdated and hold only for contingently backward compatibility. Please get rid of these outdated stuff, if it is not needed for the new version. Users/Admins may still keep these databases after upgrading, but it should not be part of the official distribution any more.
This is an easy-to-do cleanup task to improve clarity. HCL may offer a free download / sandbox portal for outdated templates, in case someone still wants them.
I've never seen anybody using these apps anyway.
Some candidates, e.g.
probably several of these certification *crt*.ntf databases
probably nntp*.ntf - no idea if someone uses this at all
There are probably several more.
