While issue 51061 is about the hex.pm importer and the rebar build 
system, this thread in only about the extracting downloader :-)

FMPOV, hex.pm is one important valid distribution point for erlang and 
elixir packages. Like PypPi is for Python and CPAN is for Perl. So we 
should support defining this as a packages source, which can also be 
used for checking for updates much easier than any git repository or 
git-based forge.

Some of the packages I've investigated so far are easier to build from 
hex.pm than from github. E.g. some github repos contain a „rebar“ binary 
(which needs to be deleted by a snippet when defining the source), while 
the corresponding hex.pm package can be used as-is.

Regarding heuristics: Since build should be reproducible, a source 
definition must not use any heuristics. Anyhow this might be useful for 
the hex.pm importer.
