So it seems system with AMD gpu need Lilu.kext and WhateverGreen.kext ver. 1.3.4 for Catalina 10.15.1 to boot.
AMD gpu is not so natively supported by OSX after all.
I don't know about other people but I can boot with out Lilu or WhateverGreen on my Z370 and Z390 systems in Mojave and Catalina, including 10.15.1.
I have Vega 56 and Radeon VII in those systems.
