Is it plan that 12.x 13.x etc continue with
provision of sig files for BETA and RC?
If so, process can be added to releng todo docs,
and the sig asc files pushed out to website,
and to download areas (https, ftp, rsync, torrent, etc)
alongside with the image datasets themselves.
If not, the docs can make note of the labels
to which sigs apply.
