Syncing across devices doesn't have to be lost just because E2E is adopted. Wire has been doing E2E chats and group chats by default (there is no non-E2E) and synchronizing chats across devices for years now.

It's just a matter of how an application has been architected and how to transition a large platform for such an addition. Neither of these are easy to change/do with Telegram's current scale. Telegram also prides itself in very fast searches since it stores messages in plaintext on its servers.

It's not like it's technically impossible for Telegram to transition to E2E as the default and only way to communicate (similar to Signal, WhatsApp and Wire).
