Last time I checked I didn't have the impression that ${PN} is not
enough to get a unique entry for a package on ctan.

Definitely, but for http/ftp listing checks SRC_URI is probably enough.
The only thing which could make it easier is when upstream uses
sub-directories for major/minor versions (like gnome for example). In
that case something like <remote-id
type="ftp">http://ftp.gnome.org/pub/GNOME/sources/GConf</remote-id>
might help to find a new version easier, but I really doubt it.

But for now I'd stick to the two cases:
a) hosting sites with project numbers/ids/names where we can extract
version information in a general way
b) arbitrary download sites, in which case a bump checker could try to
find new versions by checking for a http/ftp listing or by checking the
Changelog (<changelog>...</changelog>) which may also be a good way to
know whether something changed at upstream (and then let the developer
decide what it was)
