Webform CiviCRM 7.x-5.x
Is this extension still needed for the Webform CiviCRM 7.x-5.x branch?
5.x drops support for older versions of CiviCRM (requires at least CiviCRM v5.12). It cleans up some old code, improves stability and introduces minor new features, but otherwise you are unlikely to notice a difference between the two.
ie. I'm just curious if it cleaned up enough old code to make this extension unnecessary.
