I agree with other opinions regarding dropping sysV.
From a user perspective: Prospective users of antiX won’t be overloaded with multiple choices from which .iso to select.
From a developer perspective: It seems like there are fewer service files to create and maintain.
From a community assistance perspective: Everyone will be speaking the same language to assist/find help when their system isn’t working as expected. Rather than asking which init the problem system is using and ascertaining whether it is an init problem or a separate app problem. Personally, I dislike Artix’s method of multiple inits and downloading service files in addition to the desired programs.
For simplicity, it seems like offering an unofficial (unsupported?) spin for other init systems would be appropriate. Either way, I look forward to enjoying the fruits of your labor.
