[meta] Webform 4.x features currently missing from the YAML Form module

Problem/Motivation

YAML Form 1.x is becoming an alternative to Webforms 4.x which has not been ported to Drupal 8.

The YAML Form module's UI is based off the Webform module but the YAML Form's underlying API architecture was built from scratch. About 80-90% of the Webform's base features and functionality has been ported to the YAML Form module.

Proposed resolution

Document any Webform 4.x features currently missing from the YAML Form module and decide what needs to be implemented.
