Well, yeah honour to whom honour is due. If the LineageOS (or other distributions) source code is clean, your unofficial custom ROMs will work as well as official ones. This has been proven several times.
For me, the term “UNOFFICIAL” is a negation of “OFFICIAL”, which evokes negative associations.
After his active e-Forum time @steadfasterX built /e/OS “CUSTOM” instead of “UNOFFICIAL” (h815 & j5y17lte) and thus gave his excellent work a positive touch. Well done, @steadfasterX
Requirements for different builds:
Custom builds, Unofficial /e/OS builds, Community builds, Official /e/OS builds
