Exactly. Around 1999, I switched from 17" CRT to 14" LCD, as the sharpness of the LCD was breathtaking and made up for the smaller screen size.
1) With OMEMO, each client/device of a user has its own key, but there is no trust relationship between them or some common master key. I can verify and trust counterparty key, but then counterparty adds another client/device and i have to do manual verification again.
2) Group chats do not have group key, but one encrypt messages for each group member (pairwise), which means that everybody has to do key exchange with everybody. This does not scale, especially with 1), which means that even if membership is stable, new keys may appear. Some clients (Conversations) do not allow to send message to a group when they do not know some keys of some group members/devices, which is fail situation that happen pretty often.
You could make the same argument for Wikipedia (that webs get less traffic if people get their answers from Wikipedia article returned as the first from web search, which is based on internet sources).
