To be honest even if I were abhishek I wouldn't transfer the ownership of a reputable ROM like LineageOS to some amateur developer. Abhishek has a lot of knowledge and years of development behind him. Nothing against Aryan, but that's how things work. Anyone can build a publish a ROM, PixelExperience is nothing compared to Lineage which is the definition of custom ROMs. Lineage already made a mess in almost the same scenario for whyred and I think abhishek wouldn't want that to happen to mido. He allowed flex to build for tissot because he has a years of work and experience and he is in the Lineage team since the early days of CM. I fully approve abhishek decision .
Besides, mido has a lot of random working and non-working trees that have buggy parts on Pie, the wake up delay for an example which in my opinion is not a official worthy device. I think until someone capable shows up (I doubt) or abhishek returns, mido won't get official.
