Having a default mapping rule is already a good thing, it's a valuable
information for both sides

For instance, instead of doing my custom function to generate a RPM
out of my Python projects with the correct name,  I could use that
tool and just tell it under which flavor of Fedora or CentOS I am.

Now, if a package does not follow the convention, does each packaging
system keep the original name of the Python project somewhere ?

If so, how hard would it be to fetch this information ?
