Well it seems like over half of all Telegram users hate this feature. Durov (CEO) released a poll on his channel asking users if they like it and want to keep it or if they hate it and want it removed.
If you use Telegram, please vote to keep it. Complete control over your digital footprint is something that I, personally, think is essential and the fact that Telegram lets you have this much control says a lot about the platform.
There are still a few things it lacks like cross-platform encryption by default and not requiring a phone number for registration but this is a major step in the right direction.
