1.2.035 brings solution to conflicting changes in Magento 2.3.2 and 2.2.9 where billing address related templating structure changed for default checkout and needed new ways to be managed and to be future proof from any other under laying template changes that core upgrades might introduce.
ver_1.2.035
refactoring: magento-coding-standards verified
refactoring: instead of free payment method form detect first available payment method and use the billing address form for that method as general billing address form
