Describe the new feature or enhancement

package.__version__ is really a standard parameter, but time to time, I found some libraries that don't have version in version, but inside some package, versioning or other space.

I think we should be more flexible about this.

Describe your proposed implementation

make _soft_import, accept some extra parameter check_version, or something like this.

Describe possible alternatives

Don't implement this.
