I really don't see the point. We have lots of communication platforms because they largely have different feature sets, different strengths, weaknesses, etc.

All the compatibility shims and bridges between platforms have been largely disappointing. You reduce the experience to a lowest common denominator of features which is the worst of all worlds. The Matrix paid subscription bridges are the best implementation of this I have ever used but I still frequently check Telegram after sending from matrix because I don't have faith that my message was accurately represented on the other side. Plain text largely works fine but you have no idea if a link embed worked, if your sticker shows up properly. Even for an image, when you send in matrix, it often shows as an uncompressed image on Telegram which is sometimes what you want but usually not. But since matrix has no concept of compressed vs uncompressed images you don't get the UI to select like you do on the real Telegram client.
