The elpa importer is accurate. Manual changes are often (I would say
around 75%) required for the description field, tho.
However, the generated source URI is not reliable (see bug #46849),
which means the importer is not practical. Using it means the imported
package will need to be updated quickly.

Indeed.

Correct
