The templates live in python-apt-common (this package is not forked in Devuan).

There are two options:

1) Submit a PR to the packager/team in Debian
2) Fork the package for Devuan and maintain the appropriate information in it

My opinion is that 1) is not a good option, because the mirror list is volatile
information and that would require stable updates on a regular basis (and that
won't easily happen in Debian)

Also I have noticed that this is not existing: http://security.devuan.org/ and
MatchURI: is not proper in most cases (contents of Devuan.info)

I can help with packaging the forked python-apt-common but I can not help with
testing because I do not use aptitude.

With best regards,
